Yk43X Gas Pressure Reducer-Air Pressure Reducing Valve-Bellows Reducing Valve

YK43X gas pressure reducer-piloted piston air pressure reducing valve
Gas pressure reducing valve belongs to the piloted piston type pressure reducing valve. Consists of two parts, the main valve and pilot valve. The main valve is mainly composed of valve seat, the main valve, piston, spring and other parts. Pilot valve is mainly composed of the seat, disc, diaphragm, spring, adjusting spring and other parts.Gas pressure reducing valve structure and application:
set the outlet pressure by adjusting the spring pressure, use the diaphragm sensing outlet pressure changes, and through the piloted piston valve opening and closing to control the drive piston throttle flow area. Realize the function of reducing and sustaining pressure as a pressure controller.Application:
The air Pressure reducing valve is mainly used for gas pipeline, such as air pressure reducing valve, nitrogen pressure reducing valve, oxygen pressure reducing valve, hydrogen pressure reducing valve, pressure reducing valve, gas pressure reducing valve, LPG Regulator, decompression valve, natural gas pressure reducing valve etc.Nominal pressure PN(Mpa)1.62.546.41016Shell test pressure (Mpa)*2.43.7569.61524Seal test pressure (Mpa)1.62.546.41016Maximum inlet pressure (Mpa)1.62.546.41016Outlet pressure range (Mpa)0.1-1.00.1-1.60.1-2.50.5-3.50.5-3.50.5-4.5Pressure characteristics derivation (Mpa)ΔP2PGB12246-1989Flow characteristics derivation (Mpa)Δ P2GGB12246-1989Minimum differntial pressure (Mpa)0.150.150.20.40.81LeakageX/F(Teflon/Rubber):O Y ( metal sealing):GB12245-1989
