Direct acting pressure relief valveThe PLC direct acting pressure relief valves improve the performance of the hydraulic system in a wide range of applications. For decades, Parker’s approach to pressure relief valves in hydraulic machines of all kind has set the industry standard. Parker’s long experience in advanced hydraulic design combined with quality materials and high precision manufacturing processes result in excellent performance characteristics with fast responses and low hysteresis. The PLC valves protect hydraulic system from potentially damaging pressure peaks, while simultaneously prevent cavitation in a consumer.
