Product Overview
The PARKER 016-85108-5 / R4V03-53530A525 is a direct-operated pressure relief valve from Parker’s proven R4V series, engineered to protect hydraulic circuits by limiting maximum system pressure and safely diverting excess flow back to tank. As a pressure control valve, it utilizes a precision-ground poppet or spool and a calibrated compression spring to establish a defined cracking pressure, opening proportionally to relieve overpressure events and reseating cleanly once system pressure falls below the set threshold. This valve serves as a critical safety and regulation element in industrial power units, manifolds, and machine circuits, safeguarding pumps, actuators, and downstream components from pressure spikes and overload conditions.
