AT series pneumatic actuators.

OVERVIEW

AT/ATK series product is a new design made by our company. It utilized the latest technology at home and aboard. Meanwhile, It completely conforms to the latest international standard. The design also be optimized using AUTOCAD 3D Software. Benefit from the new craft, the product have high quality and reliable performance as well as good look. There are two configurations in this series, that is double acting and spring return. It includes 9 models. The customer could choose suitable Model to save cost.
1) symmetrical double-piston rack and pinion structure design, quick and stable action, high precision and high output power, is capable of reverse rotation through simple change in the installation position of the piston.

2) It has long service life and small friction coefficient, with the excellent extruded aluminum alloy cylinder, high-precision processed inner bore and hard anodized (in special situation, anodizing + Teflon coating) outer surface.

3) The integrated design and same cylinders and end caps of different models of single-acting and double-acting actuators enable changing the acting mode simply by assembling springs or disassembling springs.

4) The combined pre-loading safe spring assembly enables convenient and safe installation or reduction of springs in the process of assembly or application.

5) The two individual regulating screws fixed on the outer side of the actuator enable more precise and convenient adjustment of the opening or closing position of the valve; if it requires full-stroke adjustment, you need to fix two extra longer regulating screws on its two end caps.

6) The multi-function position indicator, with on-site visual instruction, in line with VDI/VDE3845 and NAMUR standards, is capable of installing and outputting all accessories, such the limit switch box, electric positioner and position sensor (Pepperl+Fuchs and Turck sensor).

7) The gas source interface, which is in compliance with the NRMAR standard, can be directly fixed on the NUMAR standard solenoid valve.

8) The composite bushing, piston guiding ring and the bearing of output shaft on the back of the rack can be used for preventing metal-to-metal friction, enhancing lubrication and enabling low friction and long service life.

9) All fastening pieces are made of stainless steel, and thus are corrosion-resistant for a long time.

10) The connection part is consis-tent with the latest internati-onal standard ISO5211 and DIN3337(F03-F25) specifications, and thus enable interch-anging and general installation.
