With base and lever (option)
Made of spheroidal cast iron with two or three bores for fixing a lever arrangement. Considering the in-
stallation conditions, the lever may be mounted to the output shaft in any desired position.
Swing lever
Two ball joints matching the lever, including lock nuts and two welding nuts, suitable for pipe according
to dimension sheet
Ball joints (option)
Base with four holes for fastening screwsFixing
