Specifications Caution
Parker Relief Valves are preset and factory sealed. Warranty is voided if seal is broken by customer. Maximum system operating pressure should not exceed 90% of relief valve set pressure. Pressures in excess of this value may cause weepage resulting in damage to plug and seat. Care should be taken when locating a relief valve within a piping system to keep the relief valve as far from the pump as possible. Certain pumps create an end-of-stroke spike in pressure that is not detectable by common instrumentation. These spikes could cause premature failure of the relief valve.
