Pressure Relief Valve

Pressure relief valves are mainly used in fire fighting or other water supply systems to prevent system overpressure or maintain the pressure of fire fighting water supply systems. When the fire pump is shut down, the impact of the water hammer can also be reduced. Also used in large water supply system water hammer device. A cleaning screen is provided at the inlet of the valve control system. Using the fluid characteristics, so that the large proportion of suspended particles, large diameter will not enter the control system, to ensure that the system circulation unimpeded, so that the valve can operate safely and reliably.
