Description
The Schneider Electric (Erie) VT3343G13B020 Zone Valve Assembly controls the mixing or diverting of hot and chilled water through hydronic heating and cooling coils. Installed directly into hydronic piping loops in HVAC systems using 3/4-inch inverted flare connections, the 120V motorized actuator drives the internal valve stem to manage fluid movement. Operating at a 4 Cv flow coefficient, the valve routes fluid through secondary bypass lines or directly through coil circuits based on line-voltage control signals. Regulating fluid flow controls coil heat transfer rates, maintains stable space temperatures, and supports balanced hydronic flow distribution across continuous operating cycles.
