The Bosch Rexroth DBETA-6X/P100G24K31F1V (R901389528) is a state-of-the-art industrial hydraulic valve designed for highly efficient and reliable pressure limitation in hydraulic systems. This direct-actuated proportional pressure relief valve is characterized by its integrated electronics, which allow for precise control over system pressure. The valve operates with a maximum pressure rating of 315 bar and can accommodate a maximum flow of 100 liters per minute, making it suitable for high-performance applications.
This model features a size 6 CETOP D subplate mounting connection with an NFPA T3.5.1 R2 D03 pattern and an ISO 4401 porting pattern, ensuring compatibility with standard mounting surfaces and simplifying installation. The DBETA-6X/P100G24K31F1V comes equipped with a Connector pole + PE electrical connection conforming to EN 175301-803 standards, facilitating secure and reliable electrical integration.
The valve's sophisticated design includes an integrated pressure sensor that provides real-time feedback on system pressure through an analog output signal (0 to 10 V and/or 4 to 20 mA), allowing for continuous monitoring and adjustment of the pressure settings. Users can easily adapt the valve to various applications using the onboard DIL switch, which adjusts the integrated pressure controller.
Built to handle a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types, this model is versatile in its application across different systems while ensuring optimal performance. The FKM seals enhance durability by providing resistance against potential fluid leaks or contamination.
In summary, the Bosch Rexroth DBETA-6X/P100G24K31F1V offers advanced capabilities for proportional pressure regulation in industrial hydraulic systems where precision and reliability are paramount. Its integrated electronics and sensor technology enable fine-tuned control over system pressures, ensuring efficiency and safety in operation.

General information
Proportional pressure relief valves of type DBETA are used for system pressure limitation. Operation is effected by means of proportional solenoid. The pressure is regulated by the pressure sensor and the valve electronics. Dependent on the electric command value, these valves can be used to steplessly set and adjust the system pressure to be limited. The valves mainly consist of the housing (1), the valve seat (3), the valve poppet (4), the proportional solenoid (2), the integrated electronics (7) and the pressure sensor (8).
Basic principle
The supply voltage and the command value are applied to the connector (6). Dependent on the command value, the electronics convert the input signal into 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) counteracts the hydraulic force in channel P. When the hydraulic force at the valve poppet (4) equals the solenoid force, the set pressure is reached. By increasing/reducing cross-section P to T, the pressure is maintained at the set level. The pressure sensor (8) captures the pressure in channel P and/or B and the integrated electronics (7) regulate the pressure independently of the flow. Connector (6) provides the pressure in channel P and/or B as an analog actual value (0 to 10 V and/or 4 to 20 mA). If the command value is zero, the control electronics only applies the minimum control current to the proportional solenoid (2) and the minimum set pressure is applied. With the DIL switch (9) the integrated pressure controller can be adjusted to various applications.

Connection cable
| 1) | Connection cable:- Recommendation 6-wire, 0.75 or 1mm2 plus protective earthing conductor and screening- Connect screening to PE on supply side only- Maximum admissible length 100 m The minimum supply voltage at the power supply unit depends on the length of the supply line (see diagram) |
| 2) | To comply with the requirements of the EMC directive 2004/108/EC, the metal version mating connector (R900223890) and a screened cable are required. |
Function
The electronics are supplied with voltage via ports A and B. The command value is applied to the differential amplifier ports D and E. The actual pressure value is captured by the integrated pressure sensor. The pressure command value is processed in the controller and compared to the actual pressure value. The power output stage processes the control output of the controller and controls the solenoid current. The actual pressure value is reported at port F (reference port C). With the DIL switch, the controller characteristics can be adjusted to certain applications (see "DIL switch position” table). For the system analysis, the pressure controller can be deactivated using the DIL switches. This corresponds to the function of a force-controlled pressure relief valve (DBETE).
Block diagram / pin assignment
Notice:
If the pressure sensor fails, the valve switches to controlled operation. Port PIN F reports 0 V and/or 4 mA.
Notice:
If the flow changes, the pressure controller is automatically adjusted to these operating conditions. In the first cycles, this may lead to changes in the transition behavior.
