The 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.

The PLC’s integrated anti-cavitation function is a great asset in any hydraulic systems that prevent cavitation in a system and will improve the function and life time of the hydraulic equipment. The pressure setting is permanently set at the factory to ensure reliable, tamper-proof function during a long service life. Parker’s dual-function threaded PLC valves are used by several leading manufacturers of hydraulic pumps, transmissions and mobile valves. They are available in four sizes with flow capacity up to 300 l/min.
