Webstone, a brand of NIBCO, announced a new patent-pending Boiler Vent Valve. This space-saving valve expands the utility of a boiler’s existing 3/4" pressure relief valve (PRV) port, capitalizing on its location at the top of the unit as the ideal placement for an air vent and other accessories. Its automatic air vent can be isolated for service, allowing the PRV (included with the boiler or sold separately) to operate unobstructed. Plugged FIP ports accommodate the installation of a low-water cut-off device and/or pressure gauge if so desired.
