The Viking 4 inch Model G-4000 dry pipe valve is a small profile, pilot operated valve (external reset) that is used to separate the water supply from the sprinkler piping which is pressurized with air. The pilot operated valve combines an internal diaphragm assembly that is pressurized closed with priming water, an internal check valve to isolate the sprinkler system piping and the Model A-1 Differential Valve located on the valve trim that allows the valve to operate upon loss of air pressure.
