This detailed valve actuator cutaway, depicts a common Scotch yoke-type valve actuator commonly used as a closure device on industrial 1/4-turn valves. This specialized pneumatic valve actuator is commonly found in manufacturing facilities, petro-chemical plants, power plants, refineries and other similar industrial, commercial and agricultural applications.

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.
Sectioning of actual industrial steel component (common component brands and models chosen for industrial relevancy).
