Steam Pressure reducing valves (PRV) are used in oil and gas, chemical, power, metallurgy, food field to regulate steam pressure in main line and large capacity process services. The adjustment bellows or diaphragm places downward pressure setting force directly on the control valve, can be used to maintain constant steam pressure, a steam flowmeter, or directly onto a process. It uses the medium itself to adjust the pressure and its set value can be quickly restored at will in the process of operation. They feature single seat, convenient maintenance, quick opening and closing, good sealing performance.
