Mitat

Butterfly valves are supplied with following actuator options:

- a lever or gear,- electric , pneumatic or hydraulic actuators.

Hand leverA lever is suitable for manual operation of small sizes ofbutterfly valves DN 80 to 200. The position of the disc canbe firmly fixed in any position between open and closedby the locking device incorporated. The hand lever is sup-plied positioned crosswise to the pipe with the valve closed.
