MT Series rack & pinion pneumatic actuators continue the Max-Air tradition of easy integration, flexible customization, and reliable operation. Features include two ISO bolt circle patterns drilled directly in the body, NAMUR standard mounting for accessories, and our patented ±10° adjustment for the open/closed positions, all backed by the best unlimited cycle life warranty. Try Our Proprietary LockMesh® Coating! LockMesh® has been shown to provide a cost effective compromise. It provides the chemical resistance of PTFE along with the durability of a stainless steel base layer. Click here for more info!

SS Series actuators take corrosion resistance to the extreme with all of the great engineering features that separate Max-Air from the competition. Our stainless steel actuators conform to the ISO standard which makes valve automation easy and cost effective. Max-Air Technology’s dual patented travel stops allow up to 110° of stroke in a 90° actuator, providing exceptional positioning adjustment.

UT 180° actuators offer an extended range of rotation beyond 90° quarter turn applications. Double acting actuators can be ordered in custom lengths between 120° and 180°, or extended travel stops can be used on the stock 180° actuator to adjust travel anywhere between 0° and 180°. Spring return actuators are available in a standard configuration (0°-180° travel, spring return to one end) or in “center return” configuration (0° ± 90° travel, spring return to the center). UT 180° actuators offer the same patented dual travel stop design (excluding 3 Position DA) w/ extended travel stop options and multiple mounting options for the ultimate flexibility.

The Max-Air line of technopolymer actuators are designed to withstand the most extreme environments (Hydrocarbons, Organic Solvents, and Fuels). Available in three sizes, your applications requiring plastics and corrosion resistance are covered with up to 500 in-lbs of torque (Double–Acting).

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.

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.

Max-Air offers a declutchable override gear with triple epoxy coated IP67 housing mounts between ISO 5211 valve and actuator interfaces. It features an easy declutch mechanism, integrated block and bleed capability and lockout/tagout holes. GOW Series comes standard with a female double square output drive, which directly couples to square valve stems, or quickly adapt to smaller square drives, or double-D and keyed drives with the use of adapter bushings.

Direct ISO 5211 valve mounting for easy and compact handwheel operation. The GO Series comes standard with a female double square output drive, which directly couples to square valve stems, or quickly adapt to smaller square drives, or double-D and keyed drives with the use of adapter bushings.
