WALTER brand F8050 Upstream Pressure Relief/Sustaining Valve is hydraulic controlled, pilot-controlled, Pressure relief valve designed to maintain constant upstream pressure within close limits. that valve installed in derivation from the main line, will relief the excessive upstream pressure when it rises above the pre-set and adjustable value.  This valve can be used for pressure relief, pressure sustaining, back pressure functions in a by-pass system. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. Operation is completely automatic and pressure settings may be easily changed by adjusting screw on top of the pilot.
WALTER brand Pressure Relief Valve is designed to reduce head loss, throttling noise and cavitation damage also and it's extremely versatile and can be used for a wide range of applications in combination with several accessories and additional functions

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.
4.Various pilots and accessories available for configuration into many different applications.
5.Special V-Port is options, please consult factory.
