The Bosch Rexroth DBET-6X/315YG24-8K4V (R901308350) is a high-performance industrial hydraulic valve designed for reliable pressure limitation in hydraulic systems. This direct-actuated proportional pressure relief valve operates with a seat design and utilizes an electrical actuation method with external electronics to control system pressure. The model is equipped with a proportional solenoid featuring a central thread and detachable coil, which translates electric current into mechanical force to modulate the valve poppet against the valve seat, thereby controlling the flow from port P to ports T or Y.
The DBET-6X/315YG24-8K4V is engineered for subplate mounting and conforms to ISO connection diagram standards, ensuring compatibility and ease of integration into various hydraulic systems. With its robust construction, this valve can handle a maximum operating pressure of up to 315 bar and facilitate a maximum flow rate of 8 liters per minute. The electrical connection is facilitated through a connector pole with PE according to EN standards.
Designed for precision control, the valve features individually adjustable ramps for both increasing and decreasing pressure settings, allowing fine-tuning of the command value pressure characteristic curve. The size of this component corresponds to CETOP D03 (NG6), making it suitable for various industrial applications where precise pressure control is critical.
The DBET-6X/315YG24-8K4V operates on a supply voltage of 24 VDC and features FKM seals compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. It has been designed with user-friendly characteristics in mind including its modular amplifier design available in Eurocard format or as plug-in amplifiers. With its state-of-the-art capabilities and adherence to strict quality standards, this Bosch Rexroth proportional valve represents an advanced solution for system pressure regulation tasks in demanding applications.

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%. |
