The Bosch Rexroth ZDRE6VP4-1X/50MG24N9K4M (R901252639) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a set command value. This valve is pilot-operated with a 3-way pressure reducing function and comes equipped with pressure limitation capabilities for the actuator. It features a maximum pressure rating of 350 bar, with an electrical connection via a 4-pole PE connector according to DIN EN standards.
The ZDRE6VP4-1X/50MG24N9K4M is characterized by its spool valve design, which includes a pilot control valve, proportional solenoid, and main valve assembly with the main control spool. This configuration enables precise command value-dependent setting of reduced pressure in the P channel through the proportional solenoid. The default state maintains an open connection from P to T while blocking P to P until activated.
For pressure reduction, the pilot pressure in the control chamber adjusts according to the command value, allowing hydraulic fluid flow from P to P. Pressure limitation is achieved by moving the main control spool to reduce port P's pressure when it surpasses the set level of the pilot control valve.
This particular model has specifications including size 6, suitable for subplate or sandwich plate mounting conforming to ISO standards for porting patterns. It also has an integrated electrical connector and can handle a maximum flow rate of 50 l/min. The type of actuation is electrical with external electronics, and it operates on a supply voltage of 24 VDC.
The Bosch Rexroth ZDRE6VP4-1X/50MG24N9K4M valve is well-suited for applications requiring precise pressure control in hydraulic systems and can be used in various configurations due to its versatile design and connection options. Its robust construction ensures reliability and performance in 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.

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:

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. |
