The Bosch Rexroth 4WRZ16W6-150-7X/ET/M (R901181894) is a high-grade pilot-operated proportional directional valve that is designed for controlling the flow direction and size in hydraulic systems. This particular model is a part of the WRZE series, which includes valves that are actuated by proportional solenoids. The valve features an additional port R for NG only and is constructed with a pilot control valve, main control spool, and centering spring to ensure reliable operation. In its function, when the solenoids are de-energized, the main control spool remains in the central position due to the centering spring. Upon energization of the solenoid, the main control spool can be proportionally moved by actuating solenoid b, allowing pilot oil to enter the pressure chamber and move the main control spool according to the electric input signal. This allows for precise control over hydraulic flow with progressive characteristics from P to A and B to T or vice versa. The WRZE series valves can be supplied with pilot oil either internally via port P or externally via port X, providing flexibility in system design. Additionally, these valves feature an optional manual override that must be used with caution due to potential uncontrolled machine movements. This model is designed for subplate mounting and adheres to ISO porting patterns. It is suitable for various sizes (NG6 to NG25) and can withstand a maximum operating pressure of up to 350 bar while handling maximum flow rates as specified by its size category. The component series X indicates its robust design tailored for demanding applications. It's important to note that internal leakage inherent to these valves may increase over their lifecycle; however, this does not detract from their overall effectiveness in industrial hydraulic systems where precision flow control is essential.
