Product Description
Rexroth 4WEH16E72/6HG24N9ETK4/B10 R901108754
The Rexroth 4WEH16E72/6HG24N9ETK4/B10 (Bosch Rexroth material number R901108754) is a high-performance, electro-hydraulically operated directional spool valve. It is designed for subplate mounting with a porting pattern according to ISO 4401-07-07-0-05 (NG16). This valve controls the start, stop, and direction of fluid flow. It features a 3-position, spring-centered spool (type E), operated by 24V DC high-performance wet-pin solenoids. The valve includes concealed manual overrides (type ET) for emergency operation and is intended for use in various hydraulic systems requiring reliable and precise control. The ‘B10’ suffix typically indicates specific pilot oil configurations or switching time adjustments.
