PRESSURE REDUCING VALVES
Model-AD-200 PRV
Punawa pressure reducing valve is a hydraulically driven, pilot valve-controlled control valve. Automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure.
This valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. No matter how the flow rate or pressure before the valve fluctuates and changes, the valve can reduce the pre-valve high pressure to the post-valve low pressure and keep it stable, even if the valve does not have user water. It can keep the outlet pressure stable.
