Bell & Gossett 113222 Automatic Air Vent, For: Hydronic Heating Systems

A float type vent designed to vent troublesome air from hydronic heating systems. The brass body and the non-ferrous internals provide years of reliable service. The compact design (3-1/8 x 1-7/8 in) and high operating pressure/temperature (240 deg F at 150 psig) limitations make the automatic air vent a must in any hydronic heating system.
