WALTER brand F8020 Pressure Reducing Valve is hydraulically driven and pilot valve-controlled valve. It’s 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.
WALTER brand valve is designed to reduce head loss, throttling noise and cavitation damage also.

Features:

1.Automatic operation, Top and seat ring guided stem and Nylon reinforced diaphragm assembly for long life and reliability.
2.In-line serviceable, Easy maintenance without removal from the main line.
3.Corrosion resistant stainless steel seat and disc retainer ring.
