ATD/ATS new type gear strip type pneumatic actuator contains oversea and demostic new technology and by CAD 3D model innovation and optimal design , its appearance is beautiful compact , modernize molding. It also adopt new material, new craft to make product quality and performance more reliable. Multi-specification selected is more economy ; Products with the latest international comprehensive standard specifications to meet the needs of the present and future.

Working principle of ATD double action actuator

When air pressure come cylinder two side piston chamber from gas port(A), two piston move to side of cylinder and then two side chamber air are moved out from gas prot (B) and at same time two piston gear strip with output shaft spin anti clockwise. Otherwise, When air pressure come to cylinder two side piston chamber from gas port (B),two piston move to middle of cylinder and then middle chamber air are moved from air port(A) and at same time, two piston gear strip with shaft spin clockwise. (If piston are installed relative inverse direaction,then output shaft are changed to reverse rotation, it would be double action inverse transformation )

Working principle of ATS single action actuator

When air pressure come cylinder two side piston chamber from gas port(A), two piston move to side of cylinder to force spring compress and then two side chamber air are moved out from gas prot (B) and at same time two piston gear strip with output shaft spin anti clockwise.Under air pressureand after solenoid valve transfering, two piston move to middle of cylinder and then middle chamber air are moved from air port(A) and at same time, two piston gear strip with shaft spin clockwise. (If piston are installed relative inverse direaction, when spring-reture output shaft are changed to reverse rotation, it would be single action inverse transformation)
