Fire Hydrant Gate Valve

Fire Hydrant Gate Valve

A fire hydrant gate valve is a crucial component of a fire protection water supply system. It is typically installed underground on the water main leading to a fire hydrant. Its primary purpose is for isolation, allowing maintenance crews to safely service or replace a hydrant without disrupting the entire water network. Designed for reliability, these valves are operated with a special key and are built to remain in either the fully open or fully closed position for long periods, ensuring immediate water availability during emergencies.
