The Bosch Rexroth DBET-6X/200G24K4V (R901000846) is a state-of-the-art industrial hydraulic valve designed for reliable pressure limitation in hydraulic systems. This direct-actuated proportional pressure relief valve is distinguished by its seat design and capability to steplessly set system pressure according to the electric command value signal. It features a size 6 interface, with a maximum flow rate of 200 l/min and an adjustable pressure range up to 315 bar, ensuring versatile application across various hydraulic functions.
Equipped with an electrical connection that conforms to EN 175301-803 (Connector pole + PE), the DBET-6X/200G24K4V offers easy integration into existing systems. The valve utilizes subplate mounting in accordance with ISO 4401, CETOP R35H, and NFPA T3.5.1 R2 D03 standards, facilitating straightforward installation and maintenance. The supply voltage required for operation is 24 VDC.
The DBET series valves are recognized for their precise control facilitated by the proportional solenoid with central thread and a detachable coil, which converts electrical signals into mechanical forces to modulate the valve poppet against the seat. This finely tunes the connection between ports P and T or Y, enabling accurate pressure adjustments within the hydraulic circuit.
This valve's robust construction includes FKM seals suitable for various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. Its compact design weighs approximately 2.3 kg. Additionally, it features a number of ports for connectivity and can be customized using external electronics for actuation control.
The Bosch Rexroth DBET-6X/200G24K4V is engineered to deliver high-performance regulation of system pressures in demanding industrial environments where precision and reliability 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%. |
