Bosch Rexroth 4WRZ16W1-150-50 Directional Proportional Control Valve is a size-16, pilot-operated proportional directional valve in Rexroth's 4WRZ family. It translates an electrical control signal into a proportional hydraulic output to direct actuator flow. The valve is designed for plate mounting on standard Rexroth subplates (TN10 through TN32) with ISO 4401 port patterns. For size 16, Rexroth specifies a nominal flow of up to 150 L/min. This valve provides precise directional control and variable-speed actuation in hydraulic circuits where smooth proportional response is required.
