What is a Pressure reducing valve
・The pressure reducing valve is a valve that works to reduce high pressure fluid to an optimal pressure. ・In other words, the throttling effect when the high pressure fluid passes through the valve causes a pressure loss and reduces the pressure. ・The spring inside the valve creates a flow path area according to the differential pressure, making the flow constant.
About use of pressure reducing valve
・Pressure reducing valve is used when the supply pressure is too high for the purpose of use ・It is also used as a measure to reduce water hammer.
Precautions for pressure reducing valve
・Lubricating grease is used for the O-ring of the piston part. It can not be used in places that require no oil. ・The detection tube length for external detection (PA-OR PA-ORH) should be approximately 1 m. We also recommend using a speed controller or needle valve
