White Rodgers 1361-104 2-Wire Hydronic Zone Control, 24V with Screw Terminal Wiring Panel & AUX Switch, 1-1/4" Tubing ID

These water valves provide a low cost system of zoned temperature control wherever hot water is the heating medium. In new construction, the heating piping system can be laid out to produce any number of independent temperature controlled zones by use of these valves. In existing buildings, a variety of zone heating combinations can be obtained, depending on the particular piping lay-outs. Each zone requires one water valve and one thermostat, but only one circulator is required for the entire system. New construction properly piped, will not require flow control valves, since the water valve itself performs this function. Existing construction, where flow control valves have been installed, will operate quite satisfactorily without removing the existing flow control valves.
