Key Specifications / Features
As China's leading 3-inch gate valve manufacturer, we produce high-quality valves with an ASTM B62 C83600 bronze body, designed to MSS SP-80 standards. Our DN80 valves are rated for PN20 and Class 150 LB, available with a rising or non-rising stem, and operated by a handwheel. The threaded stem moves the gate to block fluid between two seats, typically made of metal with hard-facing options like Stellite (CoCrW) or stainless steel overlay for extended durability. Soft seat options are also available for specific applications, such as water service.
