Small-bore valves utilize G/NPT thread connections, while large-bore valves adopt high-strength flange connections, perfectly matching various waterscape arts and industrial water control projects both domestically and internationally. This series of valves utilizes a semi-direct acting (also known as lift-type direct acting) control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the perfect integration of direct-acting and pilot-operated controls, possessing the rigid characteristic of zero-differential startup. When the electromagnetic coil is de-energized, the pilot hole remains closed under the action of the return spring force, and the medium enters the cavity above the main valve core through the fluid channel. Under the combined action of the main spring force and water system pressure, the diaphragm or piston assembly is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, a specially customized waterproof coil generates a powerful electromagnetic attraction force that first opens the pilot valve port, and pressure in the cavity above the main valve core begins to relieve. Simultaneously, the moving iron core of the electromagnet directly lifts the main valve core assembly upward through a specialized mechanical linkage structure. Even in an extreme zero-pressure state where the system pressure differential is 0bar (no fluid pressure), the electromagnetic force generated by the coil can directly and rigidly pull open the main valve port, achieving millisecond-level response speeds and 100% precise actuation. When a pressure differential exists in the system, the main valve port is fully opened through the collaborative thrust of electromagnetic force and fluid pressure differential, restoring large-flow unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, and the valve core assembly resets at high speed within milliseconds, completing a rapid and rigid cut-off cycle to ensure that the fountain water column achieves a crisp, drip-free, and perfect visual effect.Product Image:SLDF Underwater Solenoid Valve

The YSE-A series pilot-operated stainless steel ultra-high pressure solenoid valve (nominal diameter ranging from DN10 to DN25) is a high-end, ultra-high pressure fluid control device specially developed for ultra-high pressure, large-flow fluid transmission and extremely severe operating conditions. As a core shut-off element in ultra-high pressure automated pipeline systems, this series features deep structural optimization targeting common industry pain points under 700bar (70MPa) ultra-high static pressure and large-bore working conditions, such as the inability to open under low pressure differentials, valve core deformation under high-pressure shocks, and seal erosion under large flow rates. The entire series comes standard with high-specification SS304 stainless steel bodies and offers two highly reliable interface types: G thread and NPT thread. It is widely used in high-pressure hydrogen storage and transportation, ultra-high pressure hydraulic pump stations, aerospace ground testing, and high-end industrial cleaning systems. This series of valves utilizes a pilot-operated control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the innovative zero-differential pilot drive structure, which perfectly combines the rigid control of electromagnetic force with the fluid dynamics of the medium's own pressure differential. When the electromagnetic coil is de-energized, the pilot valve port remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the 700bar ultra-high medium pressure, the main piston is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage high-pressure shut-off. When the electromagnetic coil is energized, a specially customized high-power, super-magnetic coil instantly generates a powerful electromagnetic attraction force that first pulls open the pilot valve port. Thanks to its special forced-lift mechanism, even in an extreme zero-pressure state where the system pressure differential is 0bar, the electromagnet can directly lift the main piston mechanically via a linkage, ensuring 100% precise actuation. When a pressure differential exists in the system, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole, utilizing the huge pressure differential thrust of the fluid to push the main piston to the fully open position, restoring highly efficient, large-flow passage. Once the coil is de-energized, the electromagnetic field disappears, and the pilot hole and main piston reset downward at high speed within milliseconds, completing a rapid and rigid high-pressure cut-off cycle.Product Image:YSE-A 2/2-Way Normally Closed Ultra-High Pressure Solenoid Valve

The YSG Series Large-Calibre Pulse Solenoid Valve is a high-efficiency control valve specifically engineered for industrial automation high-flow pipelines, environmental dust collector pulsing, and mass volume fluid transport systems.

The entire lineup is integrated with high-strength flanged connections compliant with industrial standards, ensuring robust structural integrity and leakage-free sealing under conditions of high flow rates and massive jet blowing volumes. Utilizing an advanced DC pulse (Direct Current Pulse) actuation mechanism, the valve radically revolutionizes traditional operations by eliminating the need for continuous power supply to maintain an open state. It only requires a microsecond-level electrical pulse signal from the controller during the instantaneous opening and closing transitions; for the remainder of the time, the valve maintains its state via an internal mechanical and aerodynamic self-locking design. This results in exceptional low power consumption, zero heat generation, and an elongated operational lifespan.

The YSG series DC pulse type solenoid valve (nominal diameter ranging from DN15 to DN80) is a high-longevity, ultra-fast response control device specially designed and developed for automated fluid control of environmental baghouse dust collector pulse jet cleaning, agricultural spray irrigation, industrial high-frequency humidification, and instantaneous large-flow multi-phase fluid pipelines. As a core execution element in various fluid control networks and pulse jet cleaning control loops, this series features comprehensive flow channel optimization design targeting the conventional working pressure range from 0.3bar to 8bar (0.03-0.8MPa). It focuses on solving technical industry difficulties common in traditional solenoid valves, such as severe heat generation and high power consumption under long-term energized states, and vulnerability to body cracking or severe actuation response lag when enduring high-frequency instantaneous switching impacts. The valve body of this series innovatively utilizes industrial-grade high-strength reinforced nylon PA66 material (where the "SL" suffix represents specialized lightweight high-longevity versions), possessing outstanding characteristics against water hammer, mechanical vibration, and physical wear. Connection types cover G/NPT threads, high-standard flanges, and convenient unions, completely and seamlessly adapting to the diverse assembly sites of modern industrial and environmental systems. This series of valves utilizes a DC pulse (also known as bistable latching type) actuation mechanism. Its core advantages lie in astonishingly ultra-low power consumption and high-frequency millisecond-level switching. Distinct from ordinary solenoid valves that require continuous electricity to maintain an open state, the DC pulse valve integrates high-performance magnetic latching components internally. When the control system (such as a pulse controller or PLC) transmits a millisecond-level forward DC electrical pulse signal (such as DC24V, lasting several milliseconds to dozens of milliseconds) to the solenoid valve coil, the moving iron core is rapidly attracted upward by magnetic force, opening the balanced pilot hole, and the main diaphragm (or main valve core) is instantly pushed open by high-pressure fluid, thoroughly opening the valve. Subsequently, even if the coil is completely de-energized, internal permanent magnetic materials can rigidly hold the iron core in the open position. Only when the system transmits a reverse DC electrical pulse signal to the coil again will the permanent magnetic field be neutralized, and the moving iron core rapidly resets and locks under the rigid drive of an ultra-strong main spring force, completely closing the main valve port. This bistable control structure perfectly avoids insulation aging risks caused by long-term coil heating, rendering actuation responses exceptionally crisp and clean.Product Image:YSG Electromagnetic Pulse Valve

The ZCM series semi-direct acting automatic gas and low-pressure gas-liquid solenoid valve (nominal diameter ranging from DN10 to DN100) is a high-security, large-bore fluid control device specially designed and developed for automated pipeline control of gas safety, gas drainage, low-pressure large-flow, and atmospheric pressure vacuum pipelines. As a core execution element in inflammable and explosive gas pipe networks and various industrial low-pressure fluid control loops, this series features deep structural optimization targeting low pressure below 4bar (0.4MPa), zero-pressure conditions, and the chemical characteristics of specialized media like gas. It focuses on solving common industry pain points under ultra-low pressure environments, such as the inability of traditional pilot valves to open due to insufficient pressure differential, and the tendency of pure direct acting valves to overheat and burn out due to excessive coil power consumption under large-bore conditions. The series offers multiple premium valve body materials including brass, SS304 stainless steel, and heavy-duty cast iron (where JF/CF represents high-strength flange versions of different materials). Small-bore valves utilize G/NPT thread connections, while large-bore valves adopt international standard flange connections, perfectly matching urban gas boiler networks, gas power generation pipe networks, industrial kiln combustion control, low-pressure gas-liquid mixed transmission, and various industrial safety protection systems. This series of valves utilizes a semi-direct acting (also known as lift-type direct acting) control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the perfect integration of the zero-pressure differential startup characteristic of direct acting valves and the fluid dynamic assistance characteristic of pilot valves. When the electromagnetic coil is de-energized, under the rigid compression action of the return spring force, the pilot hole remains closed, and the medium enters the cavity above the main valve core (diaphragm or piston) through the fluid channel. Under the combined action of the main spring force and the gas system's own pressure, the sealing assembly is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage airtight shut-off. When the electromagnetic coil is energized, a customized electromagnetic assembly instantly generates a powerful electromagnetic attraction force that first opens the pilot hole, and pressure in the cavity above the main valve core quickly relieves to the outlet end through the pilot hole. Simultaneously, the moving iron core of the electromagnet directly pulls up the main valve core assembly through a specialized mechanical linkage lift structure. In extreme working conditions where the system pressure differential is 0bar (such as zero pressure differential, vacuum, or system startup without pressure), the electromagnetic force can directly and rigidly pull open the main valve port, achieving millisecond-level rigid actuation and precise switching. When a weak pressure differential exists in the system, the main valve port is fully opened through the collaborative thrust generated by the electromagnetic attraction force and the medium pressure differential, restoring ultra-large flow unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, and the valve core assembly resets and locks at high speed within milliseconds under the drive of the main spring force, completing a rapid and rigid safety shut-off.Product Image:ZCM Automatic Solenoid Valve for Gas and Low-Pressure Gas-Liquid

The ZCM series direct acting automatic gas and low-pressure gas-liquid solenoid valve (nominal diameter ranging from DN15 to DN200) is a high-security, heavy-duty fluid control device specially designed and developed for automated pipeline control of low pressure, atmospheric pressure, vacuum, and large flow fluids. As a core execution element in low-pressure industrial gas pipe networks and urban gas emergency safety shut-off loops, this series features deep structural optimization targeting low pressure below 4bar (0.4MPa), zero-pressure conditions, and large-bore fluid transmission. It focuses on solving common industry pain points under ultra-low pressure environments, such as sluggish actuation, pilot holes being easily clogged by medium scaling, and the extreme sealing tightness requirements for highly hazardous media like gas. The series offers multiple premium valve body materials including brass, SS304, and SS316 stainless steel. Small-bore valves utilize G/NPT thread connections, while large-bore valves adopt international standard flange connections, perfectly matching gas boiler networks, centralized gas supply safety shut-offs, industrial kiln combustion control, low-pressure water treatment environmental protection systems, and various vacuum gas-liquid control engineering. This series of valves utilizes a pure direct acting control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the fact that its action is completely independent of the medium pressure differential inside the pipeline, possessing a genuine zero-pressure differential rigid switching characteristic. When the electromagnetic coil is de-energized, the high-elasticity return spring applies direct force through the main valve shaft, driving the large-diameter sealing core downward rapidly to press it firmly against the main valve seat. Under the support of the spring's rigid force, absolutely reliable, zero-leakage physical shut-off is achieved. When the electromagnetic coil is energized, a customized high-power electromagnetic assembly instantly generates a powerful electromagnetic attraction force. This attraction force directly and rigidly overcomes the internal main spring resistance and the heavy weight of the large-diameter sealing assembly through the moving iron core, pulling open the valve core directly as a whole. The main valve port opens instantly, and the medium restores large-flow unhindered passage. Within the full series working pressure range of 0 to 4bar, whether the pipeline is in an absolute vacuum state, zero-pressure state, or low-pressure fluctuating condition, the opening and closing of the valve are directly determined by electromagnetic force and spring force. The actuation is crisp and neat, and the response time is shortened to the millisecond level, perfectly eliminating the common industry problem where traditional pilot valves fail to open or close tightly due to insufficient pressure differential.Product Image:ZCM Automatic Solenoid Valve for Gas and Low-Pressure Gas-Liquid

The ZCT Series 2-Way 2-Position Piston Type (Normally Closed) Stainless Steel Solenoid Valve is a premium, heavy-duty automatic valve engineered for modern industrial fluid control systems. Combining the outstanding corrosion resistance of precision-cast stainless steel (SS304) with an advanced piston-guided mechanical configuration, this series is custom-designed for the highly reliable automation of steam, gases, and liquids under strenuous operating conditions.Operating Principle: Being a Normally Closed (NC) valve, the internal pilot orifice remains closed when the system is de-energized. The main valve piston is pressed tightly against the seat by both the force of the return spring and the fluid pressure itself, effectively isolating the media. When the electromagnetic coil receives an electrical signal, it generates a robust magnetic field that instantly lifts the plunger, opening the pilot orifice. The fluid pressure inside the upper piston cavity is released immediately through this pilot hole, establishing a severe pressure differential across the piston. The upstream fluid pressure overcomes the combined force of the spring and piston weight, pushing the main piston upward to the fully open state. Once power is cut, the pilot orifice seals again, pressure rebuilds in the upper chamber, and the spring swiftly drives the piston downward to ensure tight shutoff.Product Image:ZCT 2-Way 2-Position Piston Type (Normally Closed) Stainless Steel Solenoid

The ZK series vacuum and low-positive-pressure dual-use solenoid valve (nominal diameter ranging from DN2.5 to DN100) is a high-airtightness, bidirectional pressure-resistant fluid control device specially designed and developed for industrial vacuum systems, negative-pressure suction networks, vacuum packaging, and atmospheric/low-positive-pressure gas-liquid circulation pipelines. As a core execution element in vacuum engineering and scientific instrument control loops, this series features comprehensive structural optimization targeting extreme negative pressure vacuum conditions from -1bar to 0bar and conventional low-positive-pressure conditions from 0bar to 1bar. It focuses on solving technical industry difficulties where ordinary industrial solenoid valves are highly prone to reverse suction leakage under vacuum negative pressure, diaphragms being sucked flat in reverse, and the inability to actuate properly under completely zero pressure differential environments. The series adopts direct acting drive for small-bore valves and semi-direct acting linkage drive for large-bore valves. It offers multiple premium valve body materials including brass and SS304 stainless steel (where JF represents high-strength flange versions), and interfaces cover G/NPT thread and standard flanges, widely matching vacuum smelting, medical negative pressure suction, semiconductor vacuum equipment, food packaging machinery, and low-pressure fluid environmental treatment core industrial fields. This series of valves utilizes pure direct acting or semi-direct acting mechanisms based on the bore size, belonging to the normally closed automatic valve type. Its core advantage lies in the fact that its opening and closing are completely independent of the medium pressure differential inside the pipeline, possessing excellent bidirectional sealing performance. When the electromagnetic coil is de-energized, the high-elasticity return spring applies direct force through the main valve shaft, driving the specialized vacuum-type sealing core downward rapidly to press it firmly against the main valve seat. Whether the upstream end of the valve is in an absolute vacuum state of -1bar or the downstream end has a slight positive pressure within 1bar, the specialized dynamic sealing pair structure can rigidly counteract interference brought by the bidirectional pressure differential, achieving tight dead shut-off with an ultra-low leakage rate. When the electromagnetic coil is energized, a specially customized heavy-duty electromagnetic assembly generates a powerful electromagnetic attraction force. For small-bore direct acting valves (such as ZK-025, etc.), the electromagnetic force directly overcomes the spring force to lift the valve core, achieving microsecond-level switching. For large-bore semi-direct acting valves (such as DN15~100 specifications), the moving iron core first opens the pilot hole to balance the cavity pressure through an internally specialized back-kick linkage structure, and then rigidly lifts the entire main valve core assembly. Even in an extreme condition where the system is in an absolute pure vacuum state without any pressure differential, the valve can be thoroughly pulled open by the mechanical linkage, the main valve port opens instantly, and the medium restores large-flow unhindered passage. Once the coil is de-energized, the mechanical structure resets at high speed within milliseconds, perfectly eliminating the common industry problem where traditional valves actuate sluggishly or fail to actuate under negative pressure vacuum conditions.Product Image:ZK Vacuum Solenoid Valve

The ZW series threaded semi direct acting solenoid valve is an industrial grade universal automated fluid shut off valve designed for general process pipelines. To satisfy distinct fail safe operations and logical parameters of modern processing manifolds, this series is explicitly split into Normally Closed and Normally Open configurations. The Normally Closed configuration maintains a leak tight isolate position when de-energized and opens instantly when energized; conversely, the Normally Open configuration sustains an unobstructed path when de-energized and drives the internal core downward to isolate flow immediately upon electrical activation. The paramount technical attribute of this series is its semi direct acting structural design, which mechanically links the electromagnetic moving plunger directly to the self balancing main sealing assembly, combining the dual advantages of direct acting and pilot operated mechanisms. This linked layout allows both NC and NO configurations to completely eliminate the strict requirement of traditional pilot valves for a minimum system differential pressure, securing zero pressure drop lightweight startup and agile isolation even under gravity fed or low pressure states, while effectively overcoming the technical limitations of standard direct acting valves which suffer from insufficient driving force under high velocity fluid impacts. The valve body is available in two rugged material options, high density premium brass and precision cast stainless steel SS304, equipped with highly versatile internal thread connections of multiple international standards. Powered by heavy duty electromagnetic coils and precision manufactured self balancing internal components, it performs reliably across a nominal pressure spectrum of zero to ten bar and operating temperatures from minus twenty to sixty five degrees Celsius, delivering dependable remote automated control and long term tight isolation for automated manifold systems and industrial equipment integration.Product Image:ZW 2-Way 2-Position Semi-Direct Acting Solenoid Valve
