Pressure Reducing Valve (PRV) is designed to reduce high upstream pressure to a precise, preset, stable downstream pressure, so to maintain the desired pressure in fire pipeline. It is a kind of globe style pilot operated valve to open or close automatically, and no need change flow rate or vary inlet pressure. Due to its exceptional reliability and low head loss it is ideal for control of fire pump discharge. It is also well‐suited to prevent over‐pressure in sprinklers, hose stations, and other discharge devices. It is intended to automatically maintain the outlet “set pressure” (static and residual) within a close range, regardless of fluctuations in the higher pressure inlet line or varying flow rates.
It is available in different dia inches of 4” & 6”.
