The Bosch Rexroth ZDBEE6VP2-2X/50G24K31A1M (R901340988) is a high-performance industrial hydraulic valve designed for reliable pressure limitation in accordance with a command value signal. This pilot-operated proportional pressure relief valve is crafted to seamlessly integrate into hydraulic systems, ensuring precise control over system pressure. With its electrical actuation featuring integrated electronics, this valve offers a convenient and efficient solution for managing hydraulic pressure.
The ZDBEE6VP2-2X/50G24K31A1M boasts a maximum pressure rating of 350 bar and can handle a maximum flow of 50 liters per minute, making it suitable for demanding applications. It features a spool symbol P T and is equipped with a Connector pole PE according to EN 175301-803-A for the electrical connection, ensuring compatibility with standard industry connectors.
Designed for sandwich plate mounting, the valve conforms to ISO 4401 and DIN 24340 porting patterns, allowing for ease of integration into various systems. The model also complies with CE electromagnetic compatibility regulations, ensuring safe operation within EU standards. Its analog connectivity accepts command values ranging from 0 to 10 volts.
The unit's construction includes NBR seals that are compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. Weighing in at approximately 3.5 kg, this robust valve is designed to withstand the rigors of industrial environments while providing precise control over hydraulic system pressures.
The ZDBEE6VP2-2X/50G24K31A1M's internal design features include a proportional solenoid that translates electric currents into mechanical force proportionally. The pilot control stage comprises the solenoid itself along with the poppet and valve seat components. Meanwhile, the main stage houses both the housing and main spool insert assembly.
To ensure optimal performance and prevent system issues, it is recommended that tank lines are not allowed to run empty and that a preload valve with approximately 5 bar preload pressure be installed under certain installation conditions.

The pilot-operated proportional pressure relief valves of type (Z)DBE are actuated by a proportional solenoid. The valves are used for system pressure limitation. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited. These valves basically consist of a pilot control stage and a main stage. The pilot control component consists of a proportional solenoid (1), the poppet (2), and the valve seat (3). The main stage consists of the housing (4) and the main spool insert assembly (5). The proportional solenoid converts the electric current proportionally into mechanical force. An increase of the current results in a correspondingly higher solenoid force. The system pressure is set in a command value-dependent form via the proportional solenoid (1). The pressure in channel P applied by the system acts on the right side of the main spool insert assembly (5). Simultaneously, the system pressure acts via the control line (7) which is equipped with the nozzle (6) on the spring-loaded side of the spool. Via the valve seat in the pilot line (3), the pressure at the poppet (2) in the spring chamber acts against the force of the proportional solenoid (1). When the pressure has reached the pre-set value, the poppet (3) is lifted off the seat. The pilot oil can now (depending on the version) drain externally via port A (Y) or internally into the tank, which results in a limitation of the pressure on the spring-loaded side of the main spool (5). If the system pressure continues to rise slightly, the higher pressure on the right hand side of the spool will push the spool to the left into the control position P to T. At a minimum control current (corresponds to a command value of zero), the minimum set pressure will be set.
Notice!
The tank lines should be prevented from running empty. With corresponding installation conditions, a preload valve (preload pressure approx. 1 bar) must be installed.
Type DBE
The pilot-operated proportional pressure relief valves of type (Z)DBEE are actuated by a proportional solenoid. The valves are used for system pressure limitation. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited. These valves basically consist of a pilot control stage and a main stage. The pilot control component consists of a proportional solenoid (1), the poppet (2), and the valve seat (3). On the proportional solenoid, there is moreover a housing (10) with the control electronics. Supply and command value voltage are applied at the connector (11). At the factory, the command value pressure characteristic curve is adjusted with little manufacturing tolerance. The main stage consists of the housing (4) and the main spool insert assembly (5). The proportional solenoid converts the electric current proportionally into mechanical force. An increase of the current results in a correspondingly higher solenoid force. The system pressure is set in a command value-dependent form via the proportional solenoid (1).

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.
