Bosch Rexroth DBE 20-37 200XYK4-509 Hydraulic Proportional Pressure Relief Valve

The Bosch Rexroth DBE 20-37 200XYK4-509 Hydraulic Proportional Pressure Relief Valve is a proportional relief device in Rexroth’s DBE family that limits hydraulic system pressure in response to an electrical control signal. The suffixes in the model, including K4, denote a connector variant used with this configuration, while 200XY indicates the pressure/port configuration associated with this exact valve. It is rated for a maximum relief pressure of 200 bar, enabling precise, proportional pressure control in compact hydraulic circuits. This valve is designed to protect hydraulic components and help stabilize operating pressure in industrial and mobile hydraulic systems that rely on external control electronics to set the relief level.
