The MF series of quarter turn actuators provide a second stage gear reduction for multi turn actuator drives to meet torques and operating times required by the industry. The cast iron construction and the rugged design of the Mastergear “MF” series range of valve actuators has been engineered to meet the arduous requirements demanded of industrial environments with corrosion resistant treatment of bare metal surfaces and the use of lip seals. The “M” range is sealed to IP67 and achieves exceptional durability. All models use high performance axial needle roller bearings, which combined with one piece worm shaft, maximise the available mechanical advantage and overall unit efficiency.
