This detailed valve actuator cutaway, depicts a common rack and pinion-type pneumatic valve actuator commonly used as a closure device on industrial 1/4-turn, including ball valves, butterfly valves and plug valves. This specialized pneumatic valve actuator is commonly found in oil& gas production applications, petro-chemical plants, power plants, refineries and other similar industrial, commercial and manufacturing applications.

Rack and Pinion pneumatic actuators are a compact, popular and economical choice for remote ball, plug, and butterfly valve actuation in many industries due to their simplicity of construction, small space envelope, linear torque transmitting characteristics, throttling capabilities, and limited number of moving parts.

The device includes a formed-steel mounting assembly, allowing for stand-alone display, bench-top mounting, or mounting on specialized mounting benches, support, display, and storage structures.

Through careful sectioning, the complete internal configuration of the actuator can be seen, while also allowing for disassembly for more complete inspection. All primary features have been retained, allowing for basic maintenance training. The conversion from linear pneumatic thrust to rotary output force can easily be seen.
