Manual Operation
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. Through corrosion
resistant treatment of bare metal surfaces, a 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 a
one-piece input wormshaft, maximizes the available mechanical
advantage and overall unit efficiency.
