Electrical connection
The valve may be switched both with relay changeover contact (3-point control signal) or with
continuous phase and N/O relay (2-point control signal, virtual return spring).

rotation. Consequently, 3 wires are required for switching the valve.
No earth connection is required, because the drive unit is safety insulated.
