    1 design and principle of operation the electric actuators basically consist of a reversible synchronous motor and a mainte- nance-free gear in a plastic housing. A cou- pling nut (4) provides a force-locking con- nection between the actuator and the plug stem of the valve. For form-fit attachment, ...

    A connected globe valve is moved to the fi- nal position (valve closed) with the fail-safe action “actuator stem extends”. Caution! Do not use the magnet for control tasks. In type 5825, there is no handwheel (2) on the housing cover. Manual override is possi- ble, after removing the front cover, us...

    3. Use a 4 mm allen key to turn the adjust- ers (7.1 or 7.2 in fig. 2) until contact is made. The angle of rotation of the cam disks is limited. Therefore, the top adjuster (7.1) should preferably be used for the upper travel range and the bot- tom adjuster (7.2) for the lower travel range. 4.2.2 po...
