2-Way Zone Valves

A 2-way zone valve has a single inlet and a single outlet, and controls the flow by means of heat-type or gear-driven motor (depending on the model). 2-way zone valves are widely used in hydronic (i.e. baseboards) and radiant floor heating applications and come in 1/2", 3/4", 1" and 1-1/4" sizes. Electrical connections are either terminal block type or wire leads.
