- Operating range DC 2...10 V
- IP 40
- Connection cable PVC 1 m
- Adjustable flow rate value
Mode of operation: The actuator moves the valve to the desired operating position at the same time as the integrated capacitors are loaded. Interrupting the supply voltage causes the valve to be moved to the emergency setting position (POP) by means of stored electrical energy , taking into account the bridging time (PF) of 1 s which was set ex-works.
Pre-charging time (start up): The capacitor actuators require a pre-charging time. This time is used for chargingthe capacitors up to a usable voltage level. This ensures that, in the event of an electricity interruption, the actuator can move at any time from its current position into the emergency setting position (POP). The duration of the pre-charging time depends mainly on how long the power was interrupted.
Delivery condition (capacitors): The actuator is completely discharged after delivery from the factory, which is why the actuator requires approximately 25 s pre-charging time before initial commissioning in order to bring the capacitors up to the required voltage level.
Simple direct mounting: Tool-free snap assembly. The actuator can be plugged on the valve by hand (Caution! Just vertical movements). Pins must match the holes on the flange. The mounting orientation in relation to the valve can be selected in 180° increments. (Possible two times)
Manual override: Click out the actuator and rotate the valve stem with the help of the actuator.
High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.
Adjustable angle of rotation: The angle of rotation of the actuator can be changed by clip in 2.5° increments. This is used to set the maximum flow rate of the valve.
kv setting: Adjustable kv-values (C2..Q- ..) / max-values (C2..QP (T) - ..) are given in the respective zone valve data sheets. 2-way valve: Remove end stop clip and place at desired position. 3-way valve: Remove end stop clip (change-over application).
