The Bosch Rexroth DBEM10-7X/200YG24K4M (R901335400) is a sophisticated pilot-operated pressure relief valve designed for hydraulic systems to limit their operating pressure. This valve enables stepless setting of the pressure based on an electrical command value, offering precise control over hydraulic operations. The DBEM10-7X/200YG24K4M consists of a main spool insert housed within the valve body, a sandwich plate valve for maximum pressure limitation, and a proportional pilot control valve that operates in conjunction with the proportional solenoid.
The functionality of this model begins with the application of pressure to channel P, which influences the main spool. Control lines fitted with nozzles lead the pressurized fluid to both sides of the main spool and the proportional pilot control valve's poppet. The balance between hydraulic force and solenoid force determines whether the poppet opens or remains closed, thereby controlling oil flow and regulating system pressure.
An integrated spring-loaded pressure relief valve serves as a safeguard against excessive pressures beyond set limits. This safety feature ensures reliable operation by releasing excess pressure into the tank when necessary. Users can adjust preset pressures through an adjustment element if required for specific applications.
Designed for subplate mounting, this model adheres to ISO porting patterns, facilitating installation and maintenance. It is also capable of being used with threaded connections for versatility in system integration. The DBEM10-7X/200YG24K4M is part of component series X and can withstand a maximum operating pressure up to bar levels specified in its documentation.
This Bosch Rexroth valve integrates seamlessly with control electronics (ordered separately) to provide a comprehensive solution for hydraulic system pressure management. It is ideal for applications requiring precise control over operating pressures within hydraulic circuits while ensuring protection against overpressure conditions.

Function, section
Valves of type DBEM are pilot-operated pressure relief valves. They are used to limit the operating pressure in hydraulic systems. These valves can be used for the stepless setting of the pressure to be limited dependent on the electrical command value. The valves basically consist of the housing (1) with main spool insert (3), the sandwich plate valve with maximum pressure limitation (2) and the proportional pilot control valve (11).
Type DBEM...
The pressure applied to channel P acts on the main spool (3). Simultaneously, the pressure at port P is applied to the spring-loaded side of the main spool (3) via the control lines (6, 7) provided with nozzles (4, 5). Via the connecting bore (9), the pressure is simultaneously applied to the poppet (10) of the proportional pilot control valve (11). The hydraulic force at the pilot poppet (10) acts against the command value-dependent force of the proportional solenoid (12). If the hydraulic force exceeds the solenoid force, the pilot poppet is opened (10). The pilot oil can now flow via the control line (13) into port Y (14) and to the tank; thus, a pressure drop results at the main spool (3) over the control lines (6, 7). The connection from port P to T is released. The main spool (3) controls the set operating pressure at port P. As hydraulic protection against inadmissibly high pressures, a spring-loaded pressure relief valve (2) has been integrated. This maximum pressure limitation is pre-set to the relevant pressure rating (see table page 6). In the operating range of the valve, the poppet (15) is held on the valve seat (17) by the spring (16) and is thus closed. If the pressure in the spring chamber of the main spool (3) exceeds the maximum admissible set pressure of the valve, the poppet (15) is pressed against the compression spring (16) and the connection into the spring chamber is opened. Via port Y (14), the pilot oil flows into the tank. Due to the control lines (6, 7), a pressure drop occurs at the main spool (3). The connection from port P to T is released. The main spool (3) controls the set maximum operating pressure in port P. Via the adjustment element (19), the pre-set pressure can be reduced, if necessary. Port Y (14) must be externally piped to the tank. The connection to the tank should be depressurized. Via port X (18), the valve may be unloaded or the maximum pressure may be limited.

Pressure in port P dependent on the command value
| 1) | 1) With valve type DBEM and 3DREM, 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%. |
