Actuator Cast Iron
1/4 Turn Gearboxes for
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.
