Airtorque Air Torque - Italy, design and manufacture a range of SIL3 rated pneumatic rack & pinion AT Series actuators in aluminium and stainless steel. Air Torque actuators operate on pressures of up to 8 bar as standard. The actuators can be operated with air or inert gas. Air Torque actuators are continuously on test.Cross-section 'Edition 2010'. They are tested to 4 million cycles! Water or bio-oil can also be used to drive the AT series if ordered with correct trim (see separate brochure for water trim). Global Supply Line are sole regional agents for Air Torque.New end cap design of the 'Edition 2010'. To view our stock list of Air Torque AT Series actuators click here.

A wide range is available in both double acting and spring return delivering torques up to 11, 000 Nm. Eighteen models provide a highly economical sizing selection. As well as conventional quarter turn actuators, Air Torque also offers actuators for special applications such as: forged stainless steel actuators, 120, 135 degree and 180 degree double acting actuators, 180 degree spring return, and 180 degree spring return with 90 degree fail safety position, as well as fast acting actuators.Safety springs of the 'Edition 2010'.

The 4th generation patented upgrade AT series permits greater product versatility for easier and reliable valve automation. Air Torque’s design is easier to maintain than other brands. The AT Series is also sold in North America as the PT series for marketing and licensing reasons only. GSL maintains substantial Air Torque inventories in our Adelaide warehouse. A full 24 month warranty is provided.

Starline Spa and Air Torque Spa are now situated in the one facility. The world’s largest compact actuator manufacturer and the world’s premier forged floating & trunnion ball valve manufacturer have now moved to the new Bergamo manufacturing facility, one of the most modern in the world. For turnkey supply of actuated valve packages a single source solution provides assurance of compatibility and quality as well as competitive, reliable delivery times.

In accordance with stringent European requirements, Air Torque actuators are under a continuously automatic cycle test programme to ensure efficiency. Air Torque actuators and all parts are 100% western European made and exclusively manufactured in Italy. 4th generation Airtorque actuators have external travel stops for open and close position adjustable from -5° to +15° and from +75° to +95°. This special feature eliminates alignment problems due to a clearance of connections between the stem of the valve adaptor and the shaft of the actuator. A triple piston bearing system provides Airtorque actuators with a constant torque, even under high loads. In addition to the guides on the outside of the piston there is an additional guide inside which absorbs the cross load through the integrated support at the drive shaft. Other available options include gear over-rides and hydraulic dampners.

Partial sterling combustion engine design

The main idea is to have the cylinders charge and detonate fuel in an computer controlled automated way as to reduce the amount of combustion cycles that would other wise be necessary to keep the engine running.
The piston is directly connected to a pneumatic actuator that extends and retracts to either draw in fresh fuel or expel exhaust gases. A charge is loaded and valves are operated pneumatically to open a path to the drive train or to exhaust spent fuel. A pressure relief valve is installed to prevent over pressure and also to direct excess cylinder pressure to a pressure tank (not shown) to be used to power actuators
