COVNA Pilot Piston Operated Pressure Reducing Valve
COVNA Stianless steel pilot piston operated pressure reducing valve (PRV) adjust the follow area of throttling part of main valve through open and close of pilot valve and drive the piston to realize the function of reducing and regulating valve. The pressure range is from 1.6 Mpa to 16 Mpa, and the pressure difference between the valve inlet and outlet pressure must ≥0.15MPa. The such pressure regulator valve is mainly applied on gas piping such as air, nitrogen, oxygen, hydrogen, liquefied gas and natural gas.
- Model: Pilot Piston Pressure Reducing Valve
- Size Range: 1/2" to 12"
- Pressure Range: 1.6 to 16 MPa
- Material: Cast Steel, Stainless Steel
COVNA Piston Operated Pressure Reducing Valve (PRV)
YK43X/F pressure reducing valve is pilot piston type, mainly composed of the main valve and pilot valve. The main valve consist of valve seat, disc, piston, cylinder, sleeve and spring. The pressure reduce valve consist of valve seat, valve flap, membrane, spring and adjusting spring.
Set the outlet pressure through adjusting spring, sense the change of pressure of outlet with membrane, adjust the follow area of throttling part of main valve through open and close of pilot valve and drive the piston to realize the function of reducing and regulating valve. The product is mainly applied on gas piping such as air, nitrogen, oxygen, hydrogen, liquefied gas and natural gas.
