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 the system pressure increases, ensuring reliable sealing in high-pressure environments.
Butt Welding (BW) Connection: Uses a butt-welding connection method compliant with the ASME B16.25 standard, ensuring reliable installation and sealing performance. It is suitable for high-pressure and medium flow rate conditions.
Swing Structure: The valve disc adopts a swing design, enabling smooth opening and closing, reducing fluid impact, and is 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: Equipped with a built-in anti-static device, which effectively prevents static accumulation, reduces the risk of fire and explosion, and is particularly suitable for controlling flammable and explosive media.
Compact Design: With a small volume and light weight, it is easy to install and integrate into existing systems, saving space.
