Profile: Automation Technology Incorporated designs & manufactures valve automation products and solutions. We start with raw steel and finish with a complete actuator package. We are accredited with ISO 9000 certification. Our piston actuators are used on all types of rising stem valves including gate valves, globe valves and rising stem ball valves. We offer both pneumatic and hydraulic actuators in spring return & double acting varieties. Our H & HDH series are piston operated valve actuators that use hydraulic pressure or high pressure gas to provide the force required to open, close and control rising stem valves. We offer a full line of power systems & can convert electrical power to hydraulic or pneumatic power to operate any actuator. We supply a full array of limit & proximity switches to meet any application requirement. The switches are rigidly attached to the actuator bracket using custom-designed switch brackets.
