Features
1、Strict Compliance with National/Industrial Standards, Suitable for High-Temperature and High-Pressure Conditions: The product is designed and manufactured in strict accordance with relevant national standards and industry specifications. Its face-to-face dimensions, connection sizes, and inspection criteria meet the requirements of the domestic power and petrochemical industries, making it compatible with industrial piping systems using the GB standard system.
2、High-Quality Forged Steel Material, Excellent Pressure-Bearing Capacity: The valve body is integrally die-forged from high-quality carbon steel (e.g., A105, 25#) or alloy steel (e.g., F11, F22). This results in a dense structure with mechanical properties significantly superior to cast steel parts. It can withstand higher working pressures and temperature fluctuations, suitable for demanding conditions up to ≤450°C and pressures PN16~PN32.
3、Y-Pattern Flow Path Design, Low Flow Resistance, Superior Regulation Performance: The valve body features a Y-pattern design, with the disc positioned at an angle to the flow direction, creating a streamlined flow path. Compared to traditional stop valves, media flow is smoother with lower pressure loss. Additionally, the conical disc enables precise flow throttling and regulation during the opening and closing process, combining multiple functions in one valve.
4、Excellent Sealing, Reliable Shut-off, and Erosion Resistance: The disc and seat utilize conical sealing surfaces overlaid with cobalt-based hard alloy (e.g., Stellite) or chromium stainless steel. Precision grinding and lapping achieve a high-hardness metal-to-metal seal. The Y-pattern design aligns the media flow nearly parallel to the sealing surfaces, effectively reducing erosion from high-pressure fluids and extending the valve's service life.
5、Diverse Connection Options, Strong Adaptability: Multiple connection types are available to suit different piping standards, such as flanged (conforming to GB/T 9113), socket weld (SW), and butt weld (BW). This adapts to various piping system installation requirements, especially suitable for applications demanding high sealing integrity and safety, such as thermal power plants, petrochemical facilities, and heating networks.
6、Flexible Operation, Wide Application Range: Depending on service conditions, it can be equipped with manual (handwheel), spur gear, or electric actuators for local or remote control. Suitable for water, steam, oil, and mildly corrosive media with operating temperatures from -29°C to +425°C, it is particularly ideal for industrial piping systems requiring low flow resistance, frequent operation, or throttling/regulating functions.
