The valve type 4WRPE is a direct operated directional control valve with electric position feedback and integrated electronics (OBE).
Set-up
The valve basically consists of:
Function
The integrated electronics (OBE) compares the specified command value to the position actual value. In case of control deviations, the relevant solenoid will be activated. Due to the changed magnetic force, the control spool (2) is adjusted against the corresponding spring. Stroke/control spool cross-section is controlled proportionally to the command value. In case of a command value presetting of 0 V, the electronics adjust the control spool (2) to central position.
Error detection
In the following cases of error, the electronics will de-energize the control solenoids:
The control spool (2) is kept in the mechanical central position by the compression springs (3.1 and 3.2) (does - with symbol V - not correspond to the hydraulic central position).

Due to the changed magnetic force, the control spool (2) is adjusted against the control spring. Stroke/control spool cross-section is controlled proportionally to the command value. With a positive command value presetting, the valve opens from P to B or A to T. Negative command values lead to no change in the control spool position.

In the following cases of error, the electronics will de-energize the control solenoid:
