The Bosch Rexroth DREE6-1X/100MG24K24A1M (R901319104) is a sophisticated industrial hydraulic valve designed for reliable pressure reduction in hydraulic systems. This valve, which is part of Bosch Rexroth's high-performance range, features a size P A configuration with an electrical actuation method that includes integrated electronics. It operates on a 24 V DC supply voltage and can handle a maximum flow rate as specified by the manufacturer.
The DREE6-1X/100MG24K24A1M is equipped with a spool symbol P A and is capable of handling maximum pressures efficiently. Its design incorporates a connector pole with an Mx standard for electrical connections, ensuring secure and reliable connectivity. The product conforms to CE standards according to the EMC Directive EU, indicating its compliance with European safety regulations.
This model utilizes NBR seals and is compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The valve's construction features three main components: the pilot control valve, the proportional solenoid with control electronics, and the main valve which houses the main control spool.
The DREE6-1X/100MG24K24A1M operates by setting the reduced pressure in channel A through the proportional solenoid based on command value signals. It ensures pressure limitation by moving the main control spool in response to pressure changes in port A. When installed, this valve offers precise control over system pressures and is ideal for applications requiring accurate pressure reduction with integrated electronic control.
Designed for subplate mounting or sandwich plate design according to ISO standards, this model allows for ease of installation in various industrial settings. The type DREE model comes equipped with integrated electronics (OBE) for enhanced functionality and user convenience. With its robust construction and precision engineering, this valve stands out as an essential component for advanced fluid power applications where controlled pressure reduction is critical.

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. |
