Aspect	Description
Actuator Type	Pneumatic
Mechanism	Scotch yoke
Power Source	Compressed air
Components	Pneumatic cylinder, yoke, crankshaft, connecting rod
Operation	1. Compressed air enters the pneumatic cylinder
	2. Air pressure moves the piston back and forth
	3. The reciprocating motion of the piston is transmitted to the yoke through the connecting rod
	4. The yoke's slot and crankshaft pin engagement cause the crankshaft to rotate
Control	Actuation is controlled by adjusting the air pressure or using control valves
Advantages	1. High torque output
	2. Compact design
	3. Suitable for applications requiring linear to rotary motion conversion
Applications	1. Valve actuation in industrial processes, such as oil and gas, chemical, and water treatment industries
	2. Dampers and control mechanisms in HVAC systems
	3. Industrial automation systems and machinery

Pneumatic Scotch yoke actuator utilizes compressed air to drive the motion of the piston, which is then translated into rotary motion through the Scotch yoke mechanism. It offers high torque output, a compact design, and finds applications in various industries for valve actuation, damper control, and automation systems.
