The 4WRTE10V100L-4X/6EG24K31/A5M valve belongs to the 4WRTE Directional Control Valves series and is manufactured by Bosch Rexroth. It manages actuator direction and flow in hydraulic automation systems. The NG 10 size defines the mounting interface and makes the unit suitable for medium capacity manifolds. A spool stamped with symbol V determines the internal flow paths when the valve shifts. The linear flow characteristic means the delivered flow changes proportionally with spool stroke for precise proportional control. At a pressure differential of 5 bar the valve provides a rated flow of 100 l/min, covering common cylinder and motor demands. Ports A and B withstand operating pressures up to 350 bar, and the external return port T is rated for 315 bar to handle high back-pressure circuits. Separate external pilot oil supply and return lines keep pilot oil clean and stable during high-pressure operation.
Electrical termination uses the DIN EN 175201-804 connector designated K31, giving a standardized interface for the control cabinet harness. The valve accepts an A5 interface that responds to a ±10 V command signal and an enable input for controlled startup. Coils are energized from a nominal 24 VDC supply, drawing up to 1.6 A and 72 VA at peak to move the spool against hydraulic forces. The winding design tolerates temperatures up to 150 °C, enabling reliable service in hot oil environments. Because the relative duty cycle is 100 %, the spool can remain actuated continuously without mandatory cooldown periods. An IP65 enclosure protects the electrical section against dust and water jets, permitting installation on machinery exposed to wash-down or particulate contamination.
