The PS Series (DN10-50) Threaded Connection 2-Way 2-Position Pilot-operated Piston Type Steam Solenoid Valve is a heavy-duty, high-performance fluid control valve specifically engineered for the punishing environments of high-temperature, high-pressure, and frequent-switching industrial thermal pipe networks. In sectors like textile dyeing, rubber vulcanization, paper drying, district heating, and steam boiler auxiliary systems, saturated or superheated steam is utilized as an intensive heat carrier, which demands uncompromising heat resistance, sealing endurance, and transient response times from fluid components.

This series features a classic 2-way 2-position pilot-piston configuration, anchored by a precision-cast high-strength Brass or premium Stainless Steel (SS304) valve body. The internal piston assembly and primary valve seat form an incredibly tight combined metal-to-soft seal. When the solenoid coil is energized, the pilot orifice triggers an instantaneous pressure release or buildup in the upper piston chamber, forcing the differential line pressure to drive the entire piston vertically. This robust action allows the valve to open or shut off swiftly under high flow rates. With a nominal pressure rating up to 16 bar and continuous temperature capability up to 180 C, the PS series stands as an indispensable safety sentinel and high-efficiency switch in modern steam automation systems.

Dual Body Materials for Diverse Environments: Available in high-quality Brass or industrial-grade Stainless Steel (SS304) to satisfy varying budgets and corrosion-resistance profiles. The SS304 body exhibits superior resistance to particulate abrasion, chemical corrosion, and intense steam scouring, substantially multiplying service life.

Pilot-Piston Assembly Built for 16 bar Pressure: Outfitted with robust, low-friction piston rings instead of traditional elastomeric diaphragms. This guarantees highly accurate and punchy actuation across a vast pressure span of 0.1 - 16 bar. The piston design efficiently tolerates high system backpressure and completely eliminates the risk of diaphragm rupture under thermal stress.

180 C High-Temperature Sealing Technology: The critical internal sealing components and piston rings are formed from premium imported thermal-synthetic materials (such as PTFE or high-temperature fluororubber). Even when continuously baked by 180 C saturated steam, these components retain excellent physical elasticity and volumetric stability, completely eliminating internal bypass or bypass leakage.

Transient Response and Optimized Large Orifice: Spanning a complete product family from DN10 up to DN50. By leveraging the pilot-operated pressure discharge mechanism, full valve stroke transition is completed in milliseconds. The generously proportioned internal flow channels ensure minimal pressure drops and maximize steam flow volume.

Global Standard Pipe Thread Interfaces: Engineered with precision-machined G threads or NPT threads that strictly adhere to international engineering standards. The clean-cut thread profiles allow for rapid sealing on-site using PTFE tape or specialized high-temperature thread sealants, significantly slashing field installation labor hours.
