***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 4WREQ6Q5-08-2X/V4C-24PA60 (R901081738) is a direct operated proportional directional valve with integrated digital control electronics, designed for precise pressure, force, and flow control within hydraulic systems. This advanced valve is equipped with proportional solenoids featuring a central thread and detachable coil, which ensure responsive operation and easy maintenance. Users can expect a position-controlled valve control spool that contributes to the device's reliability and accuracy.
The model is capable of integrating pressure sensors, although these are optional depending on the specific application requirements. It is designed for subplate mounting with a porting pattern that conforms to ISO standards. The analog interface facilitates command and actual value signals, while the design accommodates CAN bus communication with CANopen protocol DS 301 or Profibus-DP for versatile connectivity options.
This Bosch Rexroth valve stands out for its quick commissioning capabilities via PC using the WINPED commissioning software, which aids in project planning tasks and parameterization of IFBP valves. Although not included in the delivery scope, this software can be downloaded free of charge and supports parameterization, diagnosis, and efficient data management on a PC system running Windows 98 or Windows XP.
The 4WREQ6Q5-08-2X/V4C-24PA60 has a size designation of 6 and belongs to component series X. It can withstand a maximum operating pressure of up to 315 bar and allows for a maximum flow rate of up to 60 liters per minute.
Notably, this model comes as a completely adjusted unit consisting of the valve itself along with digital control electronics and field bus connection options. This integration simplifies setup processes and enhances performance consistency across various applications. Users are advised that due to its design principle, internal leakage may occur over the product's life cycle; thus, precautions such as installing preload valves under certain conditions are recommended to maintain optimal operation.

Set-up:
Valve with integrated sensors:
The valve basically consists of:
Housing (1) and pressure sensor plate (12) with connection surface Control spool (2) with compression springs (3 and 4) and spring plates (8 and 9) Coils (5 and 6) and pole tubes (14 and 15) with central thread Position transducer (7) Integrated pressure sensors (10) Integrated digital control electronics IAC-P (11)Functional description
With de-energized solenoids (5 and 6), the control spool (2) is brought into the central position by compression springs (3 and 4) between the spring plates (8 and 9) (with V spool valve without spring plate). With V spool valves, the mechanical zero position does not correspond to the hydraulic one. Depending on the valve type, the following functions result (some of them can be combined): Flow control (Q) Flow control (Q) Pressure control in A and/or B (p) Force control (p) Substitutional control p/Q The command value presetting can alternatively be specified via an analog interface (X1) or via the field bus interface (X2, X3). The actual value signals are provided via an analog interface (X1) and can additionally be read out via the field bus (X2, X3). The controller parameters are set via the field bus Separate supply voltage for bus/controller and power part (output stage) for safety reasonsThe digital integrated control electronics enables the following error detection:
Cable break pressure sensor (10) Undervoltage Cable break position transducer (7) Communication error Watchdog Cable break command value inputs (only with current interface)The following additional functions are available:
Ramp generator Internal command value profile Enable function analog / digital Error output 24 VPC program WIN-PED 6
To implement the project planning task and to parameterize the IFB-P valves, the user may use the WIN-PED commissioning software.

Important notice:
The PG fitting (13) must not be opened. Mechanical adjustment of the adjustment nut located below is prohibited and damages the valve!
Notice!
Due to the design principle, internal leakage is inherent to the valves, which may increase over the life cycle. The tank line must not be allowed to run empty. With corresponding installation conditions, a preload valve must be installed.
