KTM Model AK & AW Pneumatic Actuators

KTM AK/AW are two high-performance pneumatic actuators under Emerson: the AK is a double rack-and-pinion type (compact, for small and medium bores), while the AW is a scotch-yoke type (high torque, for large bores). Both are suitable for 90° rotary valves (ball valves / butterfly valves), featuring stable operation, high reliability, and easy automation.

Details

Features

1.Double acting and single acting type are of the same shape and dimension (AK)

2.Double rack and pinion gear construction produces of AK a smooth uniform stroke throughout the whole range. The AW has a Scotch yoke structure and uses a double piston system to generate high output.

3.Guide rod eliminates side loading of the piston for smooth actuation and greater durability

4.Double rack design of AK allows for a larger cylinder bore and shorter piston stroke, resulting in a more compact unit and high torque

5.ISO 5211 mounting pattern to provide great flexibility for valve adaptation (AK)

6.Air supply port (piping seat) and stem top of AK conform to NAMUR standards for simple and direct mounting of accessories

7.Interchangeable spring return sets according to each operating pressure/torqe.
