Rexroth R901495957 4WREE6E16-30/V/24A1-655

Product Description

Rexroth R901495957 4WREE6E16-30/V/24A1-655

The Rexroth R901495957, also designated as 4WREE6E16-30/V/24A1-655, is a direct-operated proportional directional control valve of size NG6. It is engineered for high-precision hydraulic control, featuring electrical position feedback of the spool and integrated electronics (OBE). This valve allows for continuous adjustment of flow direction and magnitude, proportional to the analog input command signal. Designed for subplate mounting with a porting pattern according to ISO 4401-03-02-0-05, it is suitable for various industrial hydraulic applications requiring accurate and responsive flow control. The FKM seals ensure compatibility with a wide range of hydraulic fluids and operating temperatures. The integrated electronics simplify system integration and offer enhanced performance characteristics.
