Structural Features
Carbon Steel Material: The valve body is made of high-quality carbon steel (WCB), featuring high strength and good corrosion resistance. It can resist erosion from various chemical media, extending the valve’s service life.
Flange Connection: Adopts a standard flange connection method compliant with the ASME B16.5 standard, ensuring reliable installation and sealing performance.
Swing-Type Structure: The valve disc uses a swing design, enabling smooth opening and closing, reducing fluid impact, and making it suitable for medium flow rate conditions.
Bidirectional Sealing: The unique sealing design ensures reliable sealing during both forward and reverse fluid flow, effectively preventing medium leakage and guaranteeing the safe operation of the pipeline system.
Fire-Safe Design: Complies with the API 607 standard. 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.
