DP17-GVPR03 Pilot Operated Pressure Reducing Valve
Product Description
Brief Introduction.
DP17
-GVPR03
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:
T
he 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.
