PRV1000 Type Pilot Piston Steam Pressure Reducing Valve
As a professional high quality Taian PRV1000 type pilot piston steam pressure reducing valve manufacturer,we will offer you the best after-sale service.Working principle High-pressure steam enters the valve through the inlet, is filtered by the filter, and then acts on the lower part of the main valve core. By adjusting the screw to compress the spring, the diaphragm is deformed and the pilot valve is opened. The inlet pressure enters above the piston through the pilot valve, overcomes the force of the main valve spring, opens the main valve, and the steam begins to flow. The outlet pressure enters the diaphragm cavity through the sensing port. Under the action of the outlet pressure, the diaphragm reaches a balance with the force of the adjusting spring, controlling the opening degree of the pilot valve. PRV1000 type pilot piston steam pressure reducing valve regulates the flow rate above the piston by changing the opening degree of the pilot valve, thereby controlling the opening degree of the main valve and achieving a stable outlet pressure.
Specifications
