The Bosch Rexroth ZDRE6VP4-1X/100MG24N9K4M (R901252636) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a command value signal. This pilot-operated, 3-way pressure reducing valve comes with a spool valve and is capable of handling a maximum pressure of 350 bar with an impressive maximum flow rate. It features electrical actuation with external electronics and utilizes a connector pole PE according to DIN EN for its electrical connection.
The ZDRE6VP4-1X/100MG24N9K4M valve is constructed with three main components: the pilot control valve, proportional solenoid, and the main valve containing the main control spool. Its primary function is to regulate the pressure in channel P via the proportional solenoid, with its spring-loaded main control spool maintaining an initial position that opens the connection from P to T while blocking P to A when depressurized.
This sophisticated piece of hydraulic machinery allows for precise pressure reduction by building up pilot pressure in response to the command value, which then moves the main control spool allowing hydraulic fluid flow from P to A. Moreover, it also incorporates a pressure limitation feature that activates if the pressure in port P surpasses the set value; this moves the spool further left, thus opening up a connection from P to T and limiting port P's pressure.
With its size conforming to CETOP D standards, this Bosch Rexroth ZDRE6VP4-1X/100MG24N9K4M valve is suitable for subplate mounting or sandwich plate design based on ISO 4401 standards. Its design includes NBR seals ensuring compatibility with various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC types. The integrated electronics OBE (On Board Electronics) version of this model simplifies setup by eliminating external wiring for command signals. This robust component series X valve ensures optimal performance in various applications requiring precise control over hydraulic system pressures.

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.

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. |
