The Bosch Rexroth DBET-6X/315YG24-8K4V-7 (R901369047) is a state-of-the-art proportional pressure relief valve designed for precise system pressure limitation. This direct operated valve is engineered to provide remote control capabilities through a proportional solenoid, which features a central thread and a detachable coil for ease of maintenance. The valve's construction includes a robust housing, a responsive valve seat, and a poppet that work in unison to regulate hydraulic flow.
The DBET-6X/315YG24-8K4V-7 operates on the principle of converting electrical command values from control electronics into mechanical force via the solenoid coil. This force is applied to the armature plunger and subsequently to the valve poppet, which interacts with the valve seat to control fluid flow between ports P and T or Y. The system pressure can be steplessly adjusted according to the electric command value, ensuring precise pressure control within hydraulic systems.
Designed for subplate mounting with porting patterns conforming to ISO standards, this model offers flexibility for various applications. It also features an amplifier available in modular design, Eurocard format, and as a plug-in amplifier. Users can benefit from individually adjustable ramps both upwards and downwards, as well as fine-tuning of the command value pressure characteristic curve.
With its size component series X, this model can handle maximum operating pressures up to 315 bar and maximum flow rates that are suitable for diverse industrial applications requiring reliable pressure regulation. The DBET-6X/315YG24-8K4V-7 embodies Bosch Rexroth's commitment to quality and innovation in hydraulic system components.

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%. |
