Heavy duty inlet valves provide for a quick connection of the male hose coupling to the vacuum cleaning system. These parts are designed for insertion into a 2" FNPT threaded fitting adapting to a 2½" tube size. Valves have self-closing covers and are available in galvanized and stainless steel, as well as nickel plated models. The electric switch option allows for convenient operation of the system at the work location. Escutcheon plates allow for a more attractive wall installation.

The same body is used for all three valves.., only the bore varies... IV-150 and IV-200 use a slight taper for hose adapter retention. IV-180 utilizes a clip on the valve lid for retention instead. Hose adapters are constructed of heavy-duty galvanized steel.
