The Rexroth ZDR6DB2-4X/150YM is a high-performance, direct-operated 3-way pressure reducing valve designed for precise pressure control in hydraulic systems. Its sandwich plate construction allows for easy installation and integration into vertical stacking assemblies with porting patterns according to ISO 4401-03-02-0-05. This valve is engineered to reduce the pressure in a specific circuit branch to a set level, which is adjustable up to 150 bar. It features an integrated pressure relief function to protect the secondary circuit from excessive pressure and a built-in check valve (Y) for free flow from port B to port A. The unit comes without a manual adjustment element (M), featuring a protective cap for tamper resistance and fixed settings. It is a reliable solution for maintaining constant secondary pressure regardless of fluctuations in the primary system pressure.
