This pressure-reducing valve belong to guide piston pressure-reducing valve. Made up of main valve and guide valve two parts. Main valve mainly made up of valve seat、main valve disk、piston、spring and so on. Guide valve mainly made up of valve seat、disc、diaphragm、spring、regulating spring and so on. Setting  outlet pressure by adjusting the pressure of regulating spring. Regulate the area of main valve throttling position by guide valve  hoisting driven piston., realizing pressure-reducing and pressure-regulating functions

Features:

1.       improve sensing performance of change of outlet pressure, high sensitivity, reduce differential pressure caused by change of upstream pressure and flow

2.       improve the flow line distribution,  lower the noise

3.       improve sealing structure, extend life of sealing surface

This product mainly used in steam pipeline, suitable for steam pipeline that large changes of outlet pressure and large change of flow
