Pilot Operated Pressure Relief Valve, In-line Mounting - Series R4V / R4V*P2 Threaded L-body

Parker Series R4V Pilot Operated Pressure Relief Valve – Reliable Protection in Hydraulic Systems

The Parker Series R4V and R4V*P2 pilot-operated pressure relief valves are engineered for in-line mounting with threaded ports (L-body configuration). These valves deliver reliable and precise pressure control in industrial hydraulic systems where safety and performance are critical.

The valves operate by using a pilot signal to regulate the main valve opening, resulting in:

• Precise pressure control and stability
• Minimal hysteresis and operating variability
• Energy-efficient operation with low pilot pressure requirements
• Robust construction designed for high-pressure applications
• In-line mounting for compact system integration

The Series R4V valves are ideal for applications in machinery, presses, test equipment, and other industrial hydraulic systems where reliable pressure relief is essential.

Parker ensures superior quality, precision, and long service life through rigorous manufacturing standards and material selection, even in demanding environments with high pressure and temperature fluctuations.
