Caleffi 6442 Series 644266A Straight Motorized Ball Zone Valve With With Micro-Switch, 1 in, Press, 13 Cv

Zone valves are used to automatically shut-off the flow, redirect or modulate hot and chilled water in hydronic heating and air conditioning systems. The motorized three-way diverting/mixing valve permits two-position diverting or three-way mixing with three-wire floating outdoor reset controller for injection mixing. The motorized three-way bypass valve permits a system to operate with a continuous flow regardless if the zone valve is in the open or in the by-pass position. The high flow and high close off performance characteristics of these zone valves, combined with the compact size, makes them particularly suitable to fit inside baseboard or directly in fan coil units. The 6442 Series and 6443 Series motor drives for 40 s. Power is then dropped by an internal switch. Power is required to drive in both directions. These valves are used in all types of systems because of the following characteristics.
