Schrader, the expert in engine valves, produces a safety valve for high-pressure gasoline rails. The Schrader High Pressure Relief Engine Valve (PRV) is mounted on the high-pressure gasoline rail, and exhausts gas through the return line if engine overpressure occurs. The valve is designed to be compact and easy to mount. The engine HPRV consists of a brass body, filter, ball, and seat. Special O-ring seals ensure air-tightness between the valve and engine. The seat’s cone is manufactured with high precision to ensure proper sealing with the ball: precise circularity and fine surface finish are key characteristics. The Schrader PRV is manufactured on a fully automated assembly machine with multiple poke-yokes. Each PRV is calibrated to the customer’s specific set-point requirement, 100% tested for opening and re-close pressure, and 100% leak-tested. Calibration is done at 100% pressure with special fluid. Our PRV is designed to meet every OEM performance specification. The Schrader PRV’s brass construction allows it to meet all automotive performance requirements after salt-spray exposure.
