Mastergear 'M' Series Manual Gear Operators
The cast iron construction and rugged design of the Mastergear 'M' series range of manual valve gear operators 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' series is sealed to IP67 and achieves exceptional durability. All models use high performance axial needle roller bearings, which combined with a one piece input wormshaft, maximises the available mechanical advantage and overall unit efficiency.
