Structural Features
Carbon Steel Material: The valve body is made of high-quality carbon steel (WCB), which has high strength and good corrosion resistance. It can resist the erosion of various chemical media and extend the service life of the valve.
Pressure-Sealed Design: Adopts a pressure-sealed design—sealing performance enhances as system pressure increases, ensuring reliable sealing in high-pressure environments.
Gear Operation: Equipped with a gear-operated mechanism, it provides stable opening and closing performance, reduces operating torque, and is suitable for large-diameter and high-pressure working conditions.
Flanged Connection: Uses a standard flanged connection method compliant with DIN standards, ensuring reliable installation and sealing performance.
Bidirectional Sealing: The unique sealing design ensures reliable sealing during both forward and reverse flow, effectively preventing medium leakage and ensuring the safe operation of the pipeline system.
Fire Safety Design: Compliant with the API 607 standard, the valve can maintain sealing performance even in case of fire, preventing medium leakage and ensuring system safety.
Anti-Static Device: Equipped with a built-in anti-static device, it effectively prevents static accumulation, reduces the risk of fire and explosion, and is particularly suitable for the control of flammable and explosive media.
Compact Design: With small size and light weight, it is easy to install and integrate into existing systems, saving space.
