The Advanced Actuators range of Stepping Actuators are based on widely used mechanical principles, which we have refined and improved upon to give a reliable, cost effective product available with pneumatic controls.
Generally the actuator is coupled into a pneumatic ring main provided by others. Via a series of pneumatic controls and two directional solenoid valves air is fed into one of two cylinders, which act upon a mechanical ratchet/gear wheel. The rotation of the gear wheel is selected by giving an electrical pulse to one of the two solenoid valves. Linear motion is achieved via a drive nut, which is connected to the gear wheel.
The mechanical drive mechanism can be supplied complete with drive nut threaded drive shaft, valve actuator mounting bracket and stem connector to fit directly to your valve.
