Vickers RP10A RD10A Series Valve | RP10A20BL RD10A25AL RD10A25BL | Cartridge Relief Valve

RP10A & RD10A Series Screw-in Cartridge Pressure Valves

Product Overview: The RP10A and RD10A series are high-performance, screw-in cartridge pressure control valves engineered for manifold-integrated applications. The RP10A typically functions as a pilot-operated relief valve for system pressure limitation, while the RD10A acts as a direct-acting relief or pressure control element. Renowned for their ease of installation, rapid response, and high repeatability, these valves are extensively used in mobile machinery, industrial power units, and Hydraulic Integrated Circuits (HIC). With various pressure adjustment ranges (Levels A, B, and C), users can achieve precise control from low-pressure fine-tuning to high-pressure safety protection.

Featured models: RP10A20BL, RD10A25AL, RD10A25BL, and RD10A25CL.

Key Technical Advantages:

• Compact Screw-in Design: Significantly saves space within hydraulic manifolds, reducing overall system weight and potential leak points.

• Tiered Pressure Adjustment System: * A/B/C Ranges: Provides optimized spring rates for different operating conditions, ensuring smooth adjustment and stable pressure settings.

• Superior Dynamic Performance: Optimized spool geometry ensures minimal hysteresis and ultra-fast response times during sudden flow fluctuations.

• All-Weather Durability: External surfaces feature specialized coatings for excellent corrosion resistance, suitable for salt spray or harsh outdoor environments.
