The Bosch Rexroth DBET-6X/420G24K4V (R901108319) is a direct operated proportional pressure relief valve designed for precise pressure limitation in hydraulic systems. This high-performance industrial hydraulic valve is engineered to reliably maintain system pressure at the desired level in response to an electrical command signal. It features a maximum pressure rating of 420 bar and is capable of handling a maximum flow rate, ensuring efficient operation for various applications.
Equipped with a proportional solenoid that operates with an external amplifier, the DBET-6X/420G24K4V valve allows for stepless adjustment of system pressure. The solenoid's mechanical force, generated by the electric current, acts on the valve poppet to control fluid flow between ports P and T. The design includes a subplate mounting connection according to ISO standards, ensuring compatibility and ease of integration into existing hydraulic systems.
The unit's electrical connection is facilitated via a connector pole with PE in accordance with EN standards. It offers versatility in terms of hydraulic fluids compatibility, including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. The seals are made from FKM material to ensure durability and resistance against harsh fluids.
With its advanced features like individually adjustable ramps and fine-tuning capabilities for command value pressure characteristics curves, this valve stands out as an essential component for applications that require precise control over hydraulic system pressures. The Bosch Rexroth DBET-6X/420G24K4V exemplifies robust construction and technological sophistication suitable for demanding industrial environments where reliability and accuracy are paramount.

General information
Proportional pressure relief valves of type DBET are remote control valves with seat design and are used for system pressure limitation. Operation by means of a proportional solenoid with central thread and detachable coil. The interior of the solenoid is connected to port T or Y and is filled with the hydraulic fluid. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited. The valves mainly consist of the housing (1), a proportional solenoid (2), the valve seat (3) and the valve poppet (4).
Basic principle
For the setting of the system pressure, a command value is specified at the control electronics. Dependent on the command value, the electronics actuate the solenoid coil with electric current. The proportional solenoid converts the electric current into mechanical force that acts on the valve poppet (4) via the armature plunger (5). The valve poppet (4) pushes onto the valve seat (3) and blocks the connection between port P and T or Y. If the hydraulic force on the valve poppet (4) equals the solenoid force, the valve controls the set pressure by lifting the valve poppet (4) off the valve seat (3) and thus enabling hydraulic fluid to flow from port P to T or Y. If the command value is zero, the control electronics only apply the minimum control current to the proportional solenoid (2) and the minimum set pressure is set.

Pressure in port P dependent on the command value (flow = 0.8 l/min)
| 1) | 1) With valve type DBET, the manufacturing tolerance at the external amplifier can be changed using the command value attenuator potentiometer "Gw". The digital amplifier is set using the "Limit” parameter. Here, the control current according to the technical data must not be exceeded. In order to be able to adjust several valves to the same characteristic curve, do not set the pressure higher than the maximum set pressure of the pressure rating with command value 100%. |
