More Information

Direct mounting: Straightforward direct mounting on the ball valve with only one central screw. The assembly tool is integrated in the plug-in position indication. The mounting orientation in relation to the ball valve can be selected in 90° steps.

Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).

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: Adjustable angle of rotation with mechanical end stops.

Home position: The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. The detection of the mechanical end stops enables a gentle approach to the end positions, thus protecting the actuator mechanics. The actuator then moves into the position defined by the positioning signal. Factory setting: Y2 (counter-clockwise rotation).

Adaption and synchronisation: An adaption can be triggered manually by pressing the „Adaption“ button. Both mechanical end stops are detected during the adaption (entire setting range). Automatic synchronisation after pressing the gearbox disengagement button is configured. The synchronisation is in the home position (0%).
