Product Description
Parker Denison R4V Series Pilot Operated Pressure Relief Valves
Product Overview: The Parker Denison R4V Series consists of industrial-grade pilot-operated pressure limiting valves designed for precise pressure regulation and overload protection in hydraulic systems. Covering both the compact R4V03 (NG10) and the high-flow R4V06 (NG25) sizes, these valves are engineered to maintain an exceptionally flat pressure-override curve even during significant flow fluctuations. Whether utilizing the G 1/2″ threaded ports or subplate mounting, the R4V series is a critical component in hydraulic power units, injection molding machines, and heavy-duty industrial presses, ensuring overall system safety.
Featured models on this page include the R4V03-53310A125 (016-84661-0) and the R4V06-533-10-A1 (016-87653-0).
Key Technical Advantages:
Superior Pressure Stability: The pilot-operated architecture ensures minimal pressure deviation between cracking and full flow, reducing system vibration.
High-Reliability Components: Utilizing genuine Parker Denison manufacturing processes, the hardened spools offer an extended service life under high-frequency relief conditions.
Flexible Mounting Options: Available with standard G 1/2″ threaded interfaces (for NG10/R4V03) or subplate mounting for seamless system integration.
Precise Pressure Setting: Multiple pressure stages available, allowing for micro-metering adjustments via manual handwheels or adjustment bolts.
