***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 4WREQ6Q5-32-2X/V8C-24CA60 (R901059709) is a direct operated proportional directional valve with state-of-the-art integrated digital control electronics, designed for precise pressure, force, and flow control. This valve is optimized for subplate mounting with a porting pattern according to ISO standards. It features a size of 32 and belongs to component series X, capable of handling a maximum operating pressure of 350 bar and facilitating a maximum flow of 600 l/min. The model is equipped with proportional solenoids that have central threads and detachable coils for ease of operation. The valve's control spool is position-controlled, ensuring accurate performance. Users have the option to include an integrated pressure sensor plate or connect an external pressure sensor through port X, allowing for flexible application depending on specific requirements. This Bosch Rexroth valve also supports an analog interface for command value presetting and actual value signals, as well as design compatibility with CAN bus featuring CANopen protocol DS 301 or Profibus-DP for seamless communication and integration into various industrial systems. For commissioning and parameterization, the WINPED PC software can be utilized, which facilitates project planning tasks with features like parameterization, diagnosis, and comfortable data management on a PC. The software requirements include an IBM PC or compatible system running Windows 98 or Windows XP with at least 64 MB RAM and 20 MB of available hard disk capacity. It's important to note that internal leakage is inherent to the design principle of these valves; thus appropriate measures such as installing a preload valve should be considered during installation to ensure longevity and proper function over its lifecycle. The WINPED PC program is not included in the scope of delivery but can be downloaded free of charge.

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 reasons

The 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 V

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.

Project planning and maintenance instructions

Connect the valve to the supply voltage only when this is required for the functional sequence of the machine. Do not use electrical signals provided via control electronics (e. g. "No error" signal) for switching safety-relevant machine functions (see also EN ISO 13849 "Safety of machinery – safety-related parts of control systems"). If electro-magnetic interference is to be expected, take appropriate measures ensuring the function (depending on the application, e. g. shielding, filtration). The devices have been tested in the plant and are supplied with default settings. Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to re-transfer the corresponding user parameters.
