Rexroth DBW20A2-5X/315-6EG24N9K4 Proportional Valve , 20mm Bore , 315 Bar

The Rexroth Proportional Valve DBW20A2-5X/315-6EG24N9K4 is a high-performance pilot-operated proportional relief valve widely used in industrial hydraulic systems. The valve is controlled by an electromagnetic pilot, enabling precise pressure regulation and flow control, making it suitable for applications requiring high response speed, control accuracy, and stability in hydraulic systems.

This valve is a pilot-operated relief valve with a bore size of 20 mm. The valve spool type is A2 with a maximum operating pressure of 315 bar. The electrical connection is a 24V DC power supply with an electromagnetic coil and a plug. The valve employs a pilot-controlled structure, where an electrical signal controls the movement of the pilot valve spool, thereby driving the main valve spool to achieve continuous regulation of hydraulic oil pressure and flow.

Its core advantage lies in its ability to perform proportional control, meaning it can precisely regulate the direction and speed of hydraulic actuators (such as hydraulic cylinders or motors) based on the magnitude of the input electrical signal.
