Product details

Y44H type bellows pressure reducing valveThis series of direct acting bellows pressure reducing valves belongs to direct acting bellows spring pressure reducing valves. It is mainly composed of bellows, regulating spring, valve seat, valve disc and other parts. The bellows is used to sense the pressure of the valve and drive the valve disc to change and control the valve opening to achieve pressure reduction and stabilization function. Set the outlet pressure by adjusting the regulating bolt.
This lever type steam pressure reducing valve has sensitive and balanced pressure regulating and stabilizing actions, and is suitable for use in pipelines for gas and liquid media.
1、 Main technical parameters and performance indicators of Y44H/Y-shaped direct acting bellows pressure reducing valve

Nominal pressure (MPa)	0.6	1.0	1.6
Shell test pressure (MPa)	0.9	1.5	2.4
Sealing test pressure (MPa)	0.6	1.0	1.6
Maximum import pressure (MPa)	0.6	1.0	1.6
Export pressure range (MPa)	0.05-0.4	0.1-0.8	0.1-1.0
Pressure characteristic deviation (MPa) △ P2P	GB12244-1989
