The Bosch Rexroth 4WRZ16E150-74/6EG24N9EK4/M (R900977992) is a high-performance, 2-stage proportional directional valve designed for precise control in demanding hydraulic applications. This NG16 valve features electrical position feedback of the main spool and integrated electronics (OBE), ensuring excellent accuracy and repeatability. It directly operates a pilot control valve which, in turn, controls the main stage, allowing for the precise management of flow direction and volume. Ideal for industrial systems requiring reliable and dynamic control of actuators, this valve is built for durability and high-pressure operation up to 350 bar. The integrated manual override provides an additional layer of control for setup and emergency situations.
