The SS 904L Wedge Gate Valve from our manufacturer is a high-performance valve designed in accordance with API 600 standards. It features a cast stainless steel body made from SS 904L, offering exceptional corrosion resistance and durability. With a DN300 (12-inch) size and a rating of PN10 (Class 150 LB), this valve is well-suited for handling significant flow rates and pressures. The valve is equipped with RF (Raised Face) flanged ends for secure and leak-free connections. It also includes a handwheel for manual operation.
