WALTER brand F8055 Upstream Pressure Relief Surge Anticipating Valve is hydraulic controlled, pilot-controlled, Surge Anticipating Valve is indispensable for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline. When pumping systems are started and stopped gradually, harmful surges do not occur. However, should a power failure take place, the abrupt stopping of the pump can cause dangerous surges in the system which could result in severe equipment damage. Power failure to a pump will usually result in a down surge in pressure, followed by an up surge in pressure. The surge control valve opens on the initial low pressure wave, diverting the returning high pressure wave from the system. In effect, the valve has anticipated the returning high pressure wave and is open to dissipate the damage causing surge. The valve will then close slowly without generating any further pressure surges.

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.
