The REXROTH 4WRKE25E350L-35/6EG24EK31/F1D3M is a heavy-duty industrial proportional directional valve engineered for high-response flow control in demanding hydraulic circuits. This pilot-operated, two-stage valve features a size 25 main stage with a nominal flow capacity of 350 L/min at a 35 bar pressure drop per land, providing precise, continuous modulation of flow direction and magnitude proportional to the electrical command signal. The integrated 6EG24EK31 pilot valve with 24 V DC wet-pin solenoid and position feedback ensures accurate spool positioning and repeatable performance under varying load conditions.
