The Bosch Rexroth 4WRZ 25 W325-7X/6EG24N9ETK4/D3M (R900762267) is a sophisticated pilot-operated proportional directional valve designed to control the flow direction and size with high precision. This valve is part of the WRZE series, which is known for its reliability in managing hydraulic functions through proportional solenoids. The setup of this model includes a pilot control valve with proportional solenoids and a main valve with a main control spool and centering spring. The functionality of the Bosch Rexroth 4WRZ 25 W325-7X/6EG24N9ETK4/D3M allows for smooth operation; when the solenoids are deenergized, the main control spool remains in a central position due to the centering spring. Upon energization, the pilot control valve proportionally moves the main control spool in response to an electric input signal, allowing for precise adjustment of hydraulic flow. The flow can occur from P to A and B to T or P to B and A to T R, depending on the spool’s position. This model features an additional port R only NG and offers options for both internal and external pilot oil supply via ports P or X respectively. For maintenance or emergency purposes, it includes an optional manual override that enables manual movement of the control spool without solenoid activation; however, users must be cautious as accidental activation may result in unintended machine movements. The Bosch Rexroth 4WRZ 25 W325-7X/6EG24N9ETK4/D3M is designed for subplate mounting with a porting pattern according to ISO standards. It also has an orifice-type cross-section with progressive flow characteristics that enhance its performance. Users should note that internal leakage is inherent to this type of valve design and may increase over its lifecycle. This model represents a robust solution for applications requiring precise hydraulic flow management without integrated electronics OBE (On-Board Electronics).
