General information
The high-response valve type 4WRPEH is a direct operated directional control valve with electric position feedback and integrated electronics (OBE). In the integrated electronics (OBE), 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 switching position P–B/A–T which may result in movements at the controlled component. This has to be considered in the system design.
