Rexroth Proportional Valve 4WRZE10E1-25-7X/6EG24N9ETK31/A1DM 350 Bar Cast Iron

Product Specification

Description:

The Rexroth 4WRZE10E1-25-7X/6EG24N9ETK31/A1DM belongs to the Rexroth 4WRZE series of proportional directional valves. This series of valves are pilot-operated two-stage proportional directional valves with electrical feedback functionality and an integrated electronic amplifier (OBE), enabling high-precision control of hydraulic systems. Rated flow rate: 25 L/min. Maximum operating pressure: 350 bar. Power supply voltage: 24V DC. Control method: electro-hydraulic proportional control with integrated electronic components.
Spool type: E1 type, suitable for standard flow control. Electrical connection: plug-in connection, compliant with industrial standards. Sealing material: NBR (nitrile rubber). Spring centering: Ensures stable return of the valve spool to the neutral position. This valve is driven by a proportional solenoid valve, combined with an integrated electronic amplifier, to achieve closed-loop control of the valve spool position, thereby precisely regulating the flow direction and flow rate of hydraulic oil. It is suitable for hydraulic systems with high requirements for dynamic response and control accuracy.
