The Bosch Rexroth DBEM10-7X/350YG24K4V (R901363276) is a sophisticated pilot-operated pressure relief valve designed to regulate the operating pressure within hydraulic systems. This valve supports stepless adjustment of the pressure based on the electrical command value. It comprises a housing with a main spool insert, a sandwich plate valve for maximum pressure limitation, and a proportional pilot control valve. The DBEM10-7X/350YG24K4V operates by applying pressure to channel P, which impacts the main spool and is simultaneously directed to the spring-loaded side of the main spool through control lines equipped with nozzles. The connecting bore also applies pressure to the poppet of the proportional pilot control valve. The hydraulic force on this pilot poppet opposes the force from the proportional solenoid; when it surpasses the solenoid force, it opens, allowing pilot oil to flow through control line into port Y and then to the tank, creating a pressure drop that releases the connection from port P to T. This model includes an integrated spring-loaded pressure relief valve as a safety feature against excessively high pressures, preset according to specific pressure ratings. In normal operations, this poppet remains closed under spring tension until excessive pressures push it open, enabling oil flow into the tank and reducing system pressure. For adjustments, an element is available to modify preset pressures if necessary. Port Y must be connected externally to a tank in an unpressurized manner. Additionally, port X enables unloading of the valve or limitation of maximum pressure. The Bosch Rexroth DBEM10-7X/350YG24K4V is suitable for subplate mounting with threaded connections that comply with ISO standards and incorporates both maximum pressure relief functionality and a single-source valve and control electronics system; however, external control electronics require separate ordering. The component series X can handle maximum operating pressures up to bar levels as specified in product documentation.

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%.

Set pressure dependent on the flow

Minimum set pressure with command value 0

1)	The characteristic curves apply for output pressure in T or Y = 0 bar in the entire flow range. Notice: To ensure the minimum set pressure is achieved, the pilot current must not exceed 100 mA.
