Product Overview
The Rexroth 4WRZE16E100-74/6EG24ETK31/A1D3M (Material Number R900954657) is a high-response, pilot-operated proportional directional valve from the Bosch Rexroth 4WRZE series. Engineered with an integrated digital amplifier (OBE) and position feedback, this valve delivers precise, infinitely variable control of flow direction and magnitude in proportion to an electrical command signal. The size 16 (NG16) unit features a 100 L/min nominal flow rating at a 10 bar pressure differential per metering edge, making it a cornerstone component for demanding motion control loops in industrial hydraulic systems where accurate velocity, position, and force regulation are essential.
