Main valve is mainly composed of valve seat,main valve disc,piston,spring and other parts. Pilot valve is mainly composed of valve seat ,valve clark,diaphragm,spring,adjusting spring and other components.
The pressure reducing valve has a lot of improvement based on general pressure reducing valve,enlarge piston area,changed the throttle structure,changed the form of sealing,increased over-flow area,etc., so as to improve the sensitivity,flow rate,working life.
The steam pressure reducing valve is mainly used for steam pipe , suitable for steam pipe of large flow rate,large flow changes,and large input pressure changes.
