The Rexroth ZDR6DB2-4X/75YM is a direct-operated 3-way pressure reducing valve designed for precise pressure control in hydraulic systems. As a sandwich plate valve, it is easily integrated into vertical stacking assemblies. Its primary function is to reduce the pressure in a secondary circuit, maintaining a constant, set pressure regardless of fluctuations in the main system’s pressure. This model features a pressure relief function for the secondary circuit, protecting it from excessive pressure buildup. The pressure is adjustable via a rotary knob, and this specific version includes an external pilot oil drain and a pressure gauge connection for monitoring.
