A200 Pressure reducing valve Anti cavitation design Ductile Iron Main Valve SS304 Pilot
A200 is a pressure reducing valve which 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.
