The Bosch Rexroth DBETE-6X/200YG24K31A1M (R901199690) is a state-of-the-art industrial hydraulic valve known for its precision in pressure limitation and direct actuation capabilities. This proportional pressure relief valve is designed with a seat and features integrated electronics (OBE), allowing for remote control operation. It operates via a high-performance proportional solenoid with a central thread and detachable coil, which translates electrical signals into mechanical forces to modulate the system pressure seamlessly.
The valve is engineered for subplate mounting, adhering to the ISO pattern, and is compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. The DBETE-6X/200YG24K31A1M can handle a maximum operating pressure of 315 bar and supports a maximum flow rate of 200 l/min. It also features an electrical connection that complies with EN standards utilizing a Connector pole + PE.
This Bosch Rexroth valve's functionality hinges on its ability to convert electric command values into precise hydraulic force through its solenoid coil, regulating fluid flow between ports P to T or Y. Its size is optimized for industrial applications, offering consistent performance with minimal manufacturing tolerance in the command value pressure characteristic curve.
With an electrical supply voltage requirement of 24 VDC and multiple port options, this valve ensures reliable operation across various settings. The DBETE-6X/200YG24K31A1M comes equipped with NBR seals to maintain integrity under diverse conditions. Its design facilitates easy maintenance while guaranteeing accurate pressure control in hydraulic systems where precise operations are critical.

General information
Proportional pressure relief valves of type DBETE are remote control valves with seat design and integrated electronics (OBE) 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), the valve poppet (4) and the integrated electronics (6). Supply and command value voltage are applied at the connector (7). At the factory, the command value pressure characteristic curve is adjusted with little manufacturing tolerance.
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.

Integrated electronics (OBE)
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.Via the characteristic curve generator, the command value solenoid current characteristic curve is adjusted to the valve so that non-linearities in the hydraulic system are compensated and thus, a linear command value pressure characteristic curve is created.The current controller controls the solenoid current independently of the solenoid coil resistance.The power stage of the electronics for controlling the proportional solenoid is a chopper amplifier with a clock frequency of approx. 180 Hz to 400 Hz. The output signal is pulse-width modulated (PWM). For checking the solenoid current, a voltage can be measured at the connector between pin F(+) and pin C(–) which is proportional to the solenoid current. 1 mV corresponds to 1 mA solenoid current.
