19516-711 Watson & Chalin Automatic Lift Axle Control Valve
The 19516-711 is a genuine Watson & Chalin replacement lift axle control module. It is used to lift, and drop the lift axle on a truck or trailer. It is common in applications where an electrically operated (automatic up) feature is necessary. The valve is designed to automatically move the axle into the lifted position when the truck is put into reverse, preventing costly damage. Mostly used on ridgid, non steerable lift axles. The 19516-111 is a manually controlled valve with 2 dedicated ports for the lift airbags, and 2 dedicated ports for the load air bags. It also contains a supply air port, a pre-plumbed control air port with electrically operated solenoid, and a load gauge air port.
