Whatever your application is ISC offers valves that provide peace of mind, and give your application the protection it needs. Relief valves are used to control or limit the pressure in a system or vessel which can upset instruments or equipment. Pressure sustaining valves act to maintain a desired upstream pressure to prevent “robbing” of the upper zone. In operation, the surge prevention valves protect against power failure surges or pressure waves caused by velocity changes. In addition to surge relief, this valve can be used for pressure relief, pressure sustaining, back pressure, or unloading functions in a by-pass system.
