DN200 PN40 GS-C25 Handwheel Flange Gate Valve

Structural Features

• Carbon Steel Material: The valve body is made of high-quality carbon steel (GS-C25, equivalent to 1.0619/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.

• Flanged Connection: Adopts a standard flanged connection method compliant with the EN 1092-1 standard, ensuring reliable installation and sealing performance.

• Handwheel Operation: Equipped with a handwheel operating mechanism, it provides stable opening and closing performance, suitable for manual operation. It reduces operating torque and facilitates on-site operation and maintenance.

• Packing Sealing: Uses high-quality packing for sealing, ensuring the valve's sealing performance during long-term use and preventing medium leakage.

• Fire-Safe Design: Complies with relevant fire safety standards. Even in the event of a fire, the valve can maintain sealing performance to prevent medium leakage and ensure system safety.

• Anti-Static Device: Built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion. It is particularly suitable for controlling flammable and explosive media.

• Compact Design: Small in size and light in weight, it is easy to install and integrate into existing systems, saving space.
