Max-Air Technology HD Series scotch yoke actuators are designed to be a comprehensive solution for a range of industrial, high torque applications. Our completely modular design includes a rugged high-strength center body, slide block yoke mechanism, and tensile spring compression for safe and reliable fail-safe action. Actuators can be sized and outfitted with air cylinders or high-pressure hydraulic cylinders to closely match your valve torque requirements. Manual overrides are readily available and specialty coatings upon request.
