The Ductile Iron Socket End Gate Valve is designed for direct connection to ductile iron pipes or PVC pipes with rubber gasket joints. Unlike flanged valves that require nuts, bolts, and gaskets, this valve features integral sockets on both ends that accept plain-end pipes. The joint uses a factory-installed EPDM rubber gasket inside the socket — when the pipe is pushed in, the gasket compresses to form a pressure-tight seal. This significantly reduces installation time and labor costs, especially for large-diameter buried pipelines. The valve itself features a fully rubber-encapsulated gate that provides resilient seating for zero leakage.
