Product Overview
The Rexroth ZDC32P-22/XM (Material Number: R900352039) is a high-performance sandwich plate pressure compensator engineered for integration into modular hydraulic control systems. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this component functions as a pressure control valve within a sandwich plate architecture, designed to be mounted between a directional control valve and its subplate. The ZDC series pressure compensator maintains a constant pressure differential across a metering orifice, ensuring precise and load-independent flow control regardless of system pressure fluctuations. With a size 32 (NG32) interface, this valve is suited for high-flow industrial circuits where accurate pressure compensation is critical for actuator speed stability and repeatable motion sequences.
