Product Overview
The Rexroth ZDC32P-22/XM (Material Number: R900539119) is a pilot-operated check valve designed for leak-free load holding and controlled load lowering in industrial hydraulic systems. As part of the Rexroth ZDC series, this valve is a sandwich (modular) plate design that mounts between a directional control valve and a subplate, providing a compact and efficient method of integrating load-holding functionality directly into a hydraulic manifold stack. The valve permits free flow in one direction and blocks reverse flow until a sufficient pilot pressure signal is applied to open the poppet, enabling controlled release of the actuator. With a size 32 (NG32 / CETOP 10) interface, the ZDC32P-22/XM is engineered for high-flow industrial circuits requiring reliable load security, such as those found in presses, injection molding machines, and heavy-duty lifting equipment.

Engineering Features & Advantages
- Leak-Free Load Holding: The poppet-type seat design provides virtually zero internal leakage in the blocked direction, ensuring safe and reliable load holding even during extended idle periods.
- Pilot-Controlled Release: Reverse flow is enabled only when pilot pressure acts on the poppet, allowing controlled and smooth lowering of suspended loads without sudden drops.
- Sandwich Plate Integration: The modular design mounts directly between a directional valve and subplate, eliminating the need for additional piping and reducing installation time and leakage points.
- High Flow Capacity: The NG32 size accommodates high flow rates with minimal pressure drop in the free-flow direction, making it suitable for demanding industrial circuits.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
