Fixed Liquid Level Gauges

Especially designed to provide a visible warning when containers are filled to the maximum permitted filling level. At the start of the filling operation, with the vent stemopened, the valve discharges vapor. When the maximum permitted filling level is reached, the valve discharges liquid. These valves are normally furnished with a 12”, 3/16” O.D. dip tube and incorporate a No. 54 drill size orifice. An optional instruction plate with “Stop Filling When Liquid Appears’’ may be ordered for use with these valves.
