Product Overview
The PARKER 016-95315-0 / R4R03-59111B110 is a precision-engineered pressure reducing valve from Parker’s R4R series of pilot-operated pressure control valves. This valve is designed to maintain a constant reduced outlet pressure regardless of fluctuations in inlet pressure or changes in flow demand, making it an essential component in complex industrial hydraulic systems. By regulating downstream pressure to a predetermined set point, it protects sensitive actuators, proportional valves, and instrumentation from over-pressure conditions while ensuring stable and repeatable operation. The R4R03-59111B110 is a direct-operated, spring-biased pressure reducing valve featuring a balanced spool design that provides excellent pressure regulation accuracy and minimal hysteresis across the full operating range.
