Product Overview
The Rexroth SV30PA3-4X/V (Material Number: R901137253) is a pilot-operated check valve designed for leak-free load holding and controlled flow in industrial hydraulic systems. As part of the Rexroth SV series, this valve is a modular, sandwich-style component that mounts between a directional control valve and its subplate, providing reliable blocking of flow in one direction while allowing free flow in the opposite direction. The pilot-operated design enables the valve to be opened hydraulically when system pressure is applied to the pilot port, making it ideal for applications requiring load holding, cylinder locking, or prevention of drift in vertical or clamping circuits. The SV30PA3-4X/V is engineered for high-pressure industrial use and is fully compatible with standard ISO 4401 mounting interfaces, ensuring seamless integration into existing hydraulic manifolds and power units.

Engineering Features & Advantages
- Precision Performance: The pilot-operated check valve provides zero-leak blocking in the closed direction, ensuring secure load holding and preventing actuator drift in critical positioning applications. The pilot piston opens the poppet precisely when pilot pressure is applied, allowing controlled return flow.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, the SV30PA3-4X/V features a robust housing and hardened internal components that resist wear, contamination, and pressure spikes, ensuring long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including ISO 4401 mounting patterns, making it a drop-in replacement for existing Rexroth SV series valves without modification.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
