General information
In the integrated electronics, the specified command value is compared with the position actual value. In case of control deviations, the stroke solenoid will be activated which - due to the changed magnetic force - adjusts the control spool against the spring.
Stroke/control cross-section is controlled proportionally to the command value. In case of a command value presetting of 0 V, the electronics adjusts the control spool against the spring to central position. In deactivated condition, the spring is untensioned to a maximum and the valve is in fail-safe position.
Switch-off behavior
With switched-off electronics, the valve will immediately move into the relevant secured basic position (fail-safe). In this connection, it moves through the position P–B/A–T which may result in movements at the controlled component. This has to be considered in the system design.

Notice:
Supply voltage 24 VDCnom, if 18 VDC are undershot, there will be an internal fast shut-down, comparable to “Enable OFF”.
Additionally with version “F1”:
ID – E ≥ 3 mA – Valve is active
ID – E ≤ 2 mA – Valve is deactivated.
Electrical signals provided via control electronics (e. g. actual value) must not be used to switch off safety-relevant machine functions. (See also the European standard "Safety requirements for fluid-powered systems and their components - Hydraulics", EN 982!)
