The Bosch Rexroth DBEM10-7X/100YG24K4V (R901363271) is a sophisticated pilot-operated pressure relief valve designed for hydraulic systems that require precise operating pressure limitation. The valve enables stepless setting of the pressure based on an electrical command value, ensuring optimal performance in various applications. It is comprised of a main spool insert within the housing, a sandwich plate valve for maximum pressure limitation, and a proportional pilot control valve.
The operation of the DBEM10-7X/100YG24K4V involves the applied pressure at channel P acting on the main spool while also being directed to the spring-loaded side via control lines equipped with nozzles. This same pressure influences the proportional pilot control valve's poppet against the force generated by the proportional solenoid. When hydraulic force overcomes solenoid force, it causes an opening, allowing pilot oil to flow to the tank, which in turn creates a pressure drop and activates the main spool to regulate operating pressure at port P.
To safeguard against excessive pressures, this model incorporates a spring-loaded pressure relief valve preset to specific ratings. In case of overpressure, this integrated feature opens up to allow pilot oil flow into the tank, ensuring system safety by controlling maximum operating pressures.
For adjustments, an external element can modify preset pressures as required. Ports Y and X must be externally piped to facilitate tank connection and unloading or limiting maximum pressures respectively. The DBEM10-7X/100YG24K4V is designed for subplate mounting with porting patterns according to ISO standards and includes both valve and control electronics—though external control electronics are ordered separately. This component series offers a maximum operating pressure of 315 bar, making it suitable for high-pressure applications demanding reliable performance and precise pressure management.

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%. |
