Product Name:Direct Acting Bellows Pressure Reducing Valve.Working Principle.
This reducing valve is direct acting bellows reducing valve,mainly composed of valve seat,valve flap(steel ball),corrupted tube combined component and spring.Set the outlet pressure through adjusting spring,the opening of valve flap enlarged when the outlet pressure reduced,the opening of valv flap decreased when the outlet pressure reached to the set pressure.The valve pressure of the medium acts on the area of corrupted tube and transdue to the adjusting spring,realizing the function of pressure reducing and regulating.This reducing valve is designed in meet of the need of energy saving.It has the characteristics of multi-function and light.It is widely applied on water,steam,air,oxygen,liquefied gas pipe of factory and hotel.You can adjust the pressure by rotating the plastic hand wheel,no need to use tool,the connection and installation is very convenient.The internal structure use corrugated tube,the sealing face has filtering mesh protecting device,which protect the internal parts from damage and greatly prolong the service life.Material of Main Component.
