fire hydrant landing valve

Fire hydrant landing valve is a manual stop valve connected to a building’s fire water network, allowing firefighters to control the flow of water to hoses. Key specifications include a durable body material like bronze or cast iron, a handwheel for operation, a specific inlet connection (often a flanged or threaded 2.5-inch BSP), and an outlet with an instantaneous coupling (like a 2.5-inch BS336). They are tested to high pressures, with a typical working pressure of 16 bar (232 psi) and a test pressure of 24 bar (348 psi)
