Product Overview

The PARKER R4R03-53511B510 (OEM reference 016-95314-5) is a pilot operated pressure reducing valve engineered for precise secondary circuit pressure regulation in industrial hydraulic systems. Manufactured by Parker Hannifin, this valve maintains a constant reduced outlet pressure regardless of fluctuations in the primary supply pressure or changes in flow demand. The pilot-operated design utilizes a balanced main spool controlled by a pilot stage, delivering accurate pressure control with minimal hysteresis and excellent repeatability. It is a direct fit replacement for original Parker R4R series valves and is widely deployed in circuits requiring stable, adjustable downstream pressure independent of upstream conditions.
