Product Overview
The EATON RV3-10-S-0-36 (part number 565568) is a direct-acting, spring-loaded pressure relief valve from the Eaton RV3 series, engineered to protect hydraulic circuits from overpressure conditions by diverting excess flow back to tank once the preset cracking pressure is reached. As a pressure control valve, it functions purely as a limiting and safety device within the system — it does not generate flow. The “10” size designation corresponds to a nominal 10-size (NG10 / CETOP 5) mounting interface, while the “S” suffix denotes the standard spring range for this frame size. The valve is designed for inline or subplate mounting in industrial power units, manifolds, and OEM hydraulic systems where reliable, repeatable pressure limitation is critical to protecting pumps, cylinders, and downstream components.

Engineering Features & Advantages
- Precision Pressure Limiting: Direct-acting poppet design provides fast, repeatable cracking and reseat characteristics, minimizing pressure overshoot and protecting sensitive downstream components.
- Stable Spring Performance: Calibrated spring range delivers consistent set pressure across the operating flow band, reducing nuisance cracking and drift over the service life of the valve.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal metering elements resistant to contamination-induced wear.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Eaton/Vickers OEM standards, including the 565568 catalog reference, ensuring drop-in interchangeability.
- Compact NG10 Footprint: Space-efficient subplate mounting simplifies integration into new manifold designs and retrofit installations alike.
Typical Industrial Applications
The EATON RV3-10-S-0-36 is deployed as a system safety and pressure-limiting element across a wide range of heavy industrial hydraulic circuits, including plastic injection molding machines, metallurgical presses and rolling mill stands, construction and marine hydraulic power units, and CNC machine tool hydraulic systems. It is equally suited to
