Six-way zone valve with male threaded connections Giacomini R274N

Six-way zone valve with male threaded connections Giacomini R274N

Six-way zone valves, R274 (with tail pieces) and R274N (without tail pieces), to manage the water supply to a single usage point from two different sources of thermal energy, or to easily manage 4-pipe systems (typically used in heating and cooling applications). A single valve, motorized with its actuator, can thus substitute four motorized two-way zone valves, easily resolving any complications with synchronization for the opening/closings of the two sources. The six-way zone valves allow the system change-over from heating to cooling (stem positions from 0° to 90°) and also the simultaneous closing of the supply from both sources (stem position at 45°). Valves R274 and R274N are typically used in radiant ceiling systems, in particular for the service sector, where the changeover from heating to cooling can be easily managed, even when this is required during the same day, and can be carried out independently for each zone.
