The cast iron construction and rugged design of the Mastergear “M” series range of manual valve actuators has been engineered to meet the arduous requirements demanded of industrial environments with corrosion resistant treatment of bare metal surfaces, a grey epoxy paint finish and the use of lip seals. With multiple sealing surfaces, the ‘M’ range is sealed to IP67 and achieves exceptional durability. Models M07 to M16 use high performance axial needle roller bearings, which combined with one- piece input worm shaft, maximize the available mechanical advantage and overall unit efficiency.
