Installation is very simple. All you need is an actuator, a toggle switch, some hose, and a compressed air supply (The hose can be up to 200 ft. long). The toggle switch either applies or releases air pressure to the actuator, which throws the turnout. An internal stainless steel spring in the actuator resets the turnout when pressure is released.

Usually you will want to control several turnouts; this is achieved by the use of a manifold as shown. Connecting a hose is easy, just push it over the barbed fitting for a permanent join. The user needs to provide a small compressor to supply air at 30psi to the system.





The actuator is screwed to the headblocks of the turnout and the throw pin is inserted into a hole drilled in the throwbar. Up to 1/2” movement is possible, most turnouts need about 1/4". A right angle elbow (ELL) can be fitted so the hose enters from the bottom or side.
