The Bosch Rexroth ZDREE6VP2-1X/50MG24K24A1M-6 (R901383377) is a sophisticated pilot-operated pressure reducing valve designed for precise pressure control in hydraulic systems. This valve is engineered to moderate system pressure by utilizing a proportional solenoid, which facilitates command value-dependent pressure adjustments in channel P. It features three main components: the pilot control valve, the proportional solenoid with integrated control electronics, and the main valve containing the main control spool.
The functionality of this Bosch Rexroth valve allows for accurate pressure reduction and limitation. In its default state, the spring holds the main control spool in position to enable flow from P to T while blocking flow from P to A. Upon receiving an electronic command, the valve adjusts pilot pressure in the control chamber, causing the main control spool to shift and regulate fluid flow from P to A accordingly. Should system pressure exceed predetermined levels, the spool shifts further to connect P to T, thereby limiting pressure to safe levels.
This model is suitable for subplate mounting or sandwich plate design, adhering to ISO porting patterns and ensuring compatibility with a range of installations. It is characterized by a maximum operating pressure of 350 bar and can accommodate flow rates up to 50 liters per minute. The ZDREE6VP2-1X/50MG24K24A1M-6 also includes integrated electronics OBE (On-Board Electronics), allowing for streamlined setup and operation without external controllers.
Ideal for applications requiring reliable and precise pressure management within hydraulic circuits, this Bosch Rexroth valve represents a combination of advanced engineering and robust construction suitable for various demanding operational conditions.

The valves of type ZDRE 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 P1 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 P1 to T and blocking of the connection from P to P1. 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 P1. Actuator pressure present in port P1 to the spring chamber (15) via channel (13) and nozzle (14). Increase in the pressure in port P1 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 P1 is almost identical with the set pressure at the pilot control valve (1).Pressure limitation:
If the pressure in port P1 exceeds the set pressure of the pilot control valve (1), the main control spool (4) is moved further to the left. This opens the connection from P1 to T and limits the pressure present in port P1 to the set command value.

Pressure in port A dependent on the command value (manufacturing tolerance); without flow
(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. |
