Pneumatic Actuator with 180 Degree Rotation for Your Multi-Port Valve

for multi-port valves.
So you need a pneumatic actuator with more than 90 degrees of rotation - most likely for a multi-port valve, or a custom louver or damper. Here's an excellent solution.

The simplicity and dependability of a 90 degree rotary vane actuator with a 2:1 step-up linkage mounted to the output shaft.

Kinetrol vane actuators provide factory fitted, direct mount linkage units for their models 02, 03, 05, 07, 09, 12, 14 and 16 actuators, giving a neat single unit with no mount kits or brackets. An added benefit is the linkage’s unique geometry gives constant 2:1 step-up, so that the output torque remains constant throughout the actuator's travel.

The all-steel mechanism of the linkage employs rolling contacts to minimize frictional losses and wear, and to maximize life. The linkage is lubricated for life, and encased in a robust, fully sealed die cast alloy casing. Exterior surfaces are protected by a corrosion resistant epoxy stove enamel finish. 

Standard adjustable end-stops on the 90 degree actuator can be used to set the angle of travel. The other end of the 90 degree actuator allows the full range of Kinetrol modular accessories to be fitted directly.

120 degree actuators are also available with adjustable end stops to give up to 133°.
