The Top Five Reasons Why Kinetrol is a Better Choice Than Rack and Pinion Actuators


1. Rotary vane actuators do not convert linear motion to rotary motion, unlike rack and pinion actuators. 


No additional gearing is required and no side loading is transferred to the actuator housing.

2. Vane actuator lip seals are the key for long life. 

The double opposing lip seal design, with stainless steel expanders, provides unmatched service life by using air pressure to improve the actuators seal-to-enclosure contact, and provide a “self cleaning” effect on the epoxy or PTFE internal finish.

3. The elimination of pressure bearing o-ring shaft seals. 

Rack and pinion actuators require shaft sealing o-rings that are exposed to the full supply air pressure used to operate the actuator. These o-rings wear, causing leaks, a drop in efficiency, and wasted energy through air consumption. Vane actuators' double opposing lip seals isolate the supply air pressure from the actuator shaft, requiring only a low friction bearing on the shaft.

4. Rotary vane actuators provide superior modulating accuracy. 

Because of the integral vane and shaft (machine from a single casting), lost motion or hysteresis is reduced dramatically which intern provides much tighter modulation and control. The vane actuators inherent low friction also reduces hunting and sticking.

5. Rotary vane actuator spring return units are designed to be virtually indestructible. 

Using low stress, clock springs reduces spring tension loss and metal fatigue. The housing for vane a actuator springs are sealed from the atmosphere, preventing corrosion of internal parts. Most importantly, these type of spring units provide the lowest torque loss which enables the section of smaller (less expensive) actuators.

Kinetrol Blueline Pneumatic Actuators for Foodservice Applications

Kinetrol Blueline actuator

"Blueline" series of pneumatic vane actuators from Kinetrol are designed for use in food service and beverage processing.  The actuators are intended to be installed in areas requiring harsh chemical washing-down. These areas are very tough on most pneumatic actuator types because the actuator is very often adversely affected by the caustic or acidic chemicals used in cleaning.

The Kinetrol Blueline actuator has an applied coating that meets the FDA allowance whereby "Resinous and polymeric coatings may be safely used as the food-contact surface of articles intended for use in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food ...".

Kinetrol's rotary design is based upon a single moving part which eliminates additional parts required to convert linear motion to rotary motion. This simple and innovative design provides a highly accurate and extremely reliable actuator for operating foodservice and beverage industry valves, providing outstanding cycle life, smooth and precise movement.

Kinetrol's Blueline Series offers a very economical option for use in foodservice wash-down environments and are in compliance with the Federal Food, Drug and Cosmetic Act (FDA) regulations, including 21 CR 175.300 (Code of Federal Regulations). The combination of Kinetrol's superior actuator design, coupled with the wash-down approved coating, makes a very compelling case to specify the Blueline actuator for your next food and beverage industry actuation requirement.
