What is pressure relief valve? Classification, structure & working principle of pressure reducing valve

24/06/2022

Pressure reducing valve, English name is Pressure Reducing Valve (abbreviated as PRV), is a valve line with the function of stabilizing the output pressure at a predetermined level, and the outlet pressure is always less than the inlet pressure. Pressure reducing valve is used for the purpose of adjusting the outlet pressure to the desired level, ensuring suitable for the operating pressure of the system behind the valve. The pressure relief valve is usually fitted with two pressure gauges, one to measure the inlet pressure, the other to measure the outlet pressure, making it easy for users to observe when operating the valve.
