Pneumatic Rack & Pinion Actuators
Rack and Pinion Actuators are for automation and operation of quarter-turn valves like Butterfly, Ball, and Plug valves as used in process industries like chemical, pharmaceutical, water processing, oil & gas, etc.
The Actuators are available in two constructions: Spring Return and Double Acting.
Mechanical Spring Return is for fail-safe applications and can be assembled for the “Fail-Close” or “Fail-Open” safety function.
Double Acting actuators can be used for a “Fail- In-Last-Position” safety function.
Rack and Pinion Actuators are available for a wide range of advanced applications. Most well know are the temperature-related trim kits that allow High Temperature or Low-Temperature operation.
The Good Supplier Pneumatic Rack and Pinion Actuators are designed, developed, and tested by an experienced and professional team of engineers and incorporate the latest in technology and materials available on the market today.
Thorough product and market research combined with over decades of valve design and manufacturing, results in the highest quality actuators available in the industry.
Pneumatic Actuators are generally recommended because they simplify piping arrangements and minimize environmental pollution problems. These are advantageous features when compared with hydraulically operated actuators.
Features & Benefits
⦿ Widest ranges of torque and rotation and deliver excellent mechanical efficiency, often as high as 90- 95%;
⦿ Designed with a profile that simplifies mounting options
⦿ Hollow pinion gears offer flexibility, allowing the machine’s shaft to mount through the pinion gear of the actuator, thus eliminating the need for a coupling
⦿ Accommodate large loads, unlike air cylinders, which provide force but do not support a load
⦿ The same roller bearing assembly that supports the pinion gear can also support axial loads
Also, unlike electric actuators, care required for the inflammable or explosive servicing environment is much less when Pneumatic Actuators are installed.
