Our 6-inch Cast Steel Gate Valve is engineered for superior performance and long-term reliability in demanding industrial environments. Constructed from high-grade WCB Carbon Steel (CS), this valve is built to handle high-pressure applications up to 300lb. It features a robust Raised Face (RF) Flange design for a secure and leak-free connection to your piping system.
This valve complies with the stringent API 600 standard, ensuring quality and durability. The Outside Screw and Yoke (OS&Y) design provides a clear visual indication of the valve’s open or closed position and keeps the stem threads isolated from the flow medium, reducing corrosion and wear. Equipped with a resilient seated seal, it guarantees tight shut-off and enhanced sealing performance. As an all-metal, resilient seated gate valve (RSV), it offers an optimal balance of strength and sealing efficiency.
As a leading China manufacturer, we are committed to delivering high-quality valve solutions that meet global standards. This Cast Steel RF Flange WCB 300lb Gate Valve is the trusted choice for engineers seeking a dependable 6-inch valve for critical shut-off applications.
