The REXROTH 4WRZE25W6-220-73/6EG24N9ETK31/F1D3V is a heavy-duty industrial proportional directional valve engineered for precise, continuous control of flow direction and magnitude in high-pressure hydraulic systems. As part of the Rexroth 4WRZE series, it utilizes a pilot-operated, two-stage design with a main spool position controlled by a proportional solenoid, ensuring accurate response to electrical input signals. This valve is specifically configured with a nominal flow rate of 220 L/min at a pressure differential of 10 bar, a spool type W6 (progressive flow characteristic), and a 24 V DC solenoid with integrated position feedback (EG24N9ETK31). The F1D3V suffix denotes a specific electrical interface and seal material, making it suitable for demanding industrial environments.
