Diaphragm Water Pressure Reducing Valve With Stainless Steel 304 Pilot P200
A200 is a pressure reducing valve that consists of
1. Main valve
2. Reducing pilot-P200
3. Reduce a higher inlet pressure to a stable outlet pressure
4. Regardless of variation of inlet pressure or variation of outlet flow.
6. When downstream pressure exceeds setting, pilot and main valve will close
7. V-port as an accessory. Reduced bore as an option.
Service Fields:
For water system, irrigation system.
