Brief Introduction.
DP Pilot Operated Pressure Reducing Valve, similar to Spirax Sarco Design, mainly used for steam system to reduce pressure, which is superior to normal piston type steam pressure reducing valve.
This Pilot Operated Pressure Reducing Valve has another prominent features:
The same body can be installed and exchange the voltage valve in the more than at the same time, realize temperature control, upstream pressure control, remote switch control, etc.
