Fire Protection Pressure Relief Valve (Safety Valve)

Fire Protection Pressure Relief Valves (Safety Valves) Model 50B-4KG1 (Globe) / 2050B-4KG1 (Angle) are specially designed to relieve overpressure in fire protection systems automatically.

This pilot-controlled relief valve maintains constant system pressure on pump discharge within very close limits when changes in demand occur. Operation is fully automatic and pressure settings can be easily changed. This valve can be used for pressure relief, pressure holding, back pressure, or unloading functions in bypass systems. This fast-opening, slow-closing relief valve protects against high-pressure spikes at pump start-up and shutdown by relieving excess pressure to a safe location.
