The Bosch Rexroth DBGT-2X/700VP2 (R901358101) is a high-performance industrial hydraulic valve designed for reliable pressure limitation in accordance with the command value signal. This pilot-operated valve is part of the DBGT series, known for its capability to remotely control and variably set system pressures up to 700 bar. The valve features an electrical actuation with external electronics and is equipped with a DC motor and self-locking speed reduction transmission that ensures the set pressure is maintained even in the event of a voltage failure.
The DBGT-2X/700VP2 incorporates a main valve along with an electric motor and gear as its pressure adjustment elements. The system pressure adjustment is achieved through rotation of a cam by the motor's output shaft, which varies the spring preload and consequently modulates the pressure. Hydraulic fluid compatibility includes HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types with FKM seals ensuring durability against these fluids.
Designed for subplate mounting with porting patterns according to ISO standards, this valve includes an actual value potentiometer for feedback on cam position and spring preload. An integrated amplifier type VTVRM facilitates program control. In terms of safety and reliability, this self-locking device maintains its position in case of power failure.
With a maximum operating pressure of 700 bar and maximum flow rate specified by the manufacturer's standards, this valve can also serve as a pilot control valve for high-pressure logic valves like LCT and LFT series. The DBGT-2X/700VP2 has a size designation X component series X, confirming its suitability for demanding applications where precise pressure control is essential.

General information
Proportional pressure relief valves type DBGT can be controlled remotely and serve for variable setting and limitation of system pressures up to 700 bar. The system pressure is set by means of a DC motor with self-locking speed reduction transmission. This way, the set pressure is maintained in the event of a voltage failure. Pressure relief valves of this series include a main valve (1) and electric motor (2) with gear (3) as pressure adjustment element.
Functional description
The system pressure is set by means of a DC motor (2) with speed reduction transmission (3). The output shaft of the speed reduction transmission turns the cam (4) that adjusts the preload of the spring (6) via the spring plate (5) to cause a pressure change. The pressure applied to channel P acts on the valve poppet (7). If the hydraulic force on the valve poppet exceeds the spring force, the valve regulates the set pressure by lifting the valve poppet from the valve seat (8) to enable the flow of hydraulic fluid from connection P to T. The cam position (4) and the spring preload is reported back by the actual value potentiometer (9). The integrated amplifier type VT-VRM1-1 enables program control. If the power supply is interrupted (cable break, fuse defect, short-circuit, etc.), the pressure set at the valve remains unchanged.
