Product Description
Rexroth R901014937 4WRZE16W6-150-74/6EG24N9K31/F1D3M
The Rexroth R901014937, also specified by its type code 4WRZE 16 W6-150-7X/6EG24N9K31/F1D3M (where ’74’ is a specific version within the ‘7X’ series), is a high-performance, direct operated proportional directional valve. This valve features electrical position feedback for the control spool and integrated electronics (OBE), enabling precise and responsive control of hydraulic fluid. Designed for subplate mounting, it conforms to the ISO 4401-07-07-0-05 (NG16) porting pattern. The 4WRZE series valves are commonly used in demanding industrial applications such as machine tools, presses, plastic processing machinery, and general automation, where accurate control over the direction and magnitude of fluid flow is critical. The integrated electronics simplify system design, reduce wiring, and offer enhanced diagnostic capabilities.
