The Bosch Rexroth DRE6-1X/210MG24N9K4M (R901208855) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a set command value. This component is characterized by its size, P A designation, and the ability to be operated electrically with an external amplifier. The valve operates on a 24 V DC supply voltage and features a DIN EN compliant connector pole PE for electrical connections.
The DRE6-1X/210MG24N9K4M valve is part of the product group ID and comes equipped with multiple ports, ensuring versatility in its applications. Its actuation type is electrical with external electronics, and it is designed for subplate mounting with connection diagrams conforming to both NFPA T.3.5.1 R2 D03 and ISO standards.
This model has a maximum flow rate specification and supports various types of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The seals within the valve are made from NBR material to ensure durability and longevity in various operational conditions.
The technical setup of the valve includes three main assemblies: the pilot control valve, proportional solenoid, and main valve with the main control spool. Its functionality allows for command value-dependent pressure settings in channel A through the proportional solenoid. It also features pressure reduction capabilities where pilot pressure buildup corresponds to command value inputs resulting in fluid flow from P to A.
Additionally, this model ensures pressure limitation by moving the main control spool in response to excess pressure in port A, thus maintaining set command values. This feature makes it suitable for applications requiring precise pressure control.
The Bosch Rexroth DRE6-1X/210MG24N9K4M is engineered for those needing an electrically operated way pressure reducing valve with dependable actuator pressure limitation capabilities suitable for various hydraulic systems.

Valves of type DRE are electrically pilot-operated 3-way pressure reducing valves with pressure limitation of the actuator. They are used for reducing a system pressure.
Technical set-up:
The valve consists of three main assemblies:
Pilot control valve (1) Proportional solenoid (2) Main valve (3) with main control spool (4)Function:
General function:
Command value-dependent setting of the pressure to be reduced in channel A via the proportional solenoid (2). In the depressurized port P, the spring (17) holds the main control spool (4) in the initial position. Thus, opening the connection from A to T and blocking of the connection from P to A. Pressure connection from port P to the ring channel (5). Pilot oil flows from the bore (6) to port T, via the flow controller (7), the nozzle (8) to the pilot control valve (1), the throttle gap (9) to the longitudinal groove (10) and the bores (11, 12).Pressure reduction:
Build-up of the pilot pressure in the control chamber (16) as function of the command value. Movement of the main control spool (4) to the right, hydraulic fluid flows from P to A. Actuator pressure pending in port A to the spring chamber (15) via channel (13) and nozzle (14). Increase in the pressure in port A to the set pressure of the pilot control valve (1) leads to the movement of the main control spool (4) to the left. Pressure in port A is almost identical with the set pressure at the pilot control valve (1).Pressure limitation:
If the pressure in port A exceeds the set pressure of the pilot control valve (1), the main control spool (4) is moved further to the left. Thus, opening of the connection from A to T and limitation of the pressure pending in port A to the set command value.

Supply and command value voltage or command value current are applied to the connector (19). At the factory, the command value pressure characteristic curve is adjusted with little manufacturing tolerance.Pressure reduction:

(Z)DRE
| 1) | With type (Z)DRE, the manufacturing tolerance at the external amplifier can be adjusted using the command value attenuator potentiometer "Gw". With the digital amplifier, the setting is made using the "Limit" parameter. In this connection, the control current according to the technical data must not be exceeded! In order to match several valves to the same characteristic curve, at a command value of 100%, the pressure must not exceed the maximum set pressure of the relevant pressure rating at no valve. |
