Scotch Yoke Actuators

Air or fluid powered rotary actuators for heavy duty, high torque applications.

As torques exceed those that can be handled by a rack & pinion actuator, the design of the scotch yoke actuator becomes the best cost to torque option. Max-Air provides heavy industrial and critical service scotch yoke options. The HD Series provides strength, torque, and competitive pricing for industrial applications. Our AG Series is 100% made and manufactured in Agrate Brianza (MB) Italy and is best suited for critical service applications or country of origin specific applications.

HD Series Pneumatic

Max-Air Technology Heavy Duty Series (HD) Scotch Yoke Actuators are available in two distinct configurations: SHD (symmetric) and CHD (canted) heavy duty selectable torque profiles are designed to perform in the most demanding applications based on valve requirement. Engineered to pneumatically automate all types of quarter turn valves (ball, butterfly, plug, damper), where reliably high torque outputs are necessary. Double Acting 13,367 to 2,738,990 in-lbs, Spring Return 5,328 to 1,320,215 in-lbs. Please refer to torque charts for specific details.

HHD Series Hydraulic

Max-Air Technology Hydraulic Heavy Duty Series (HHD) Scotch Yoke Actuators are available in two distinct configurations: SHD (symmetric) and CHD (canted) heavy duty selectable torque profiles are designed to perform in the most demanding applications based on valve requirement. Hydraulic power cylinders multiply actuator torque output in a more compact design and can reduce stroke times. Actuators can be converted from air to fluid power with stock or custom hydraulic cylinders

AG Series

Max Air Technology is proud to introduce the new AG Series scotch yoke actuator. Designed and manufactured 100% in Italy, this actuator is built to last with a 25-year design life. Years of manufacturing and design experience have culminated into our unique Guided-Motion concept, which provides superior performance, longevity, and flexibility. Additional details such as high-grade materials, precision machined components, and rigorous quality control all contribute to a robust construction that outperforms the competition.
