Electrohydraulic actuators SKD.. N4561
2-port valves VVF53.. N4405
The return spring causes the actuator to move to the «0%» stroke position
and closes the valve.
· Voltage on Y1 piston extends valve opens
· Voltage on Y2 piston retracts valve closes
· No voltage on Y1 piston / valve stem remain in the respective
and Y2 position
· Signal Y increasing: piston extends valve opens
· Signal Y decreasing: piston retracts valve closes
· Signal Y constant: piston / valve stem remain in the respective
position
· Override control Z see description of override control input, page 6
A frost protection thermostat or temperature detector can be connected to
the MKD..563.. control device.
The added signals from the QAF21.. and QAF61.. cannot be connected.
«Connection diagrams» for operation with frost protection thermostat or
frost protection monitor refer to page 21.
