Mitech’s pneumatic rotary actuators can be utilised in many industrial, R&D, laboratory, production and quality inspection applications which require rotary motion. These pneumatic rotary actuators can handle small to medium size payloads with rotation up to 90° and can be mounted and operated in any direction. By using the actuators, productivity is improved and costs are reduced.
The pneumatic rotary actuators are custom designed and require little maintenance. They are available with either a double crank mechanism for modulating control or a scotch yoke mechanism for on/off duty. The actuators are field-reversible from clockwise-to-close to clockwise-to-open. With their pneumatic piston design, the actuators are offered in large sizes and can be engineered and fitted to most valves up to a 250 000 Nm torque.
By utilising a square drive, the actuators can be mounted perpendicular to or inline with the pipe work and the adjustable end stops can be externally adjusted in both the open and closed position to within 7°. The single spring design which is pre-stressed in a detachable pack makes the actuator easy to assemble and disassemble. Pressure seals are all simple ‘O’ rings, reducing maintenance costs.
