Caleffi Z45 2-Way Zone Valve 3/4" Sweat 24V

The Caleffi Z45 2-Way Zone Valve helps run heating and cooling systems by moving water as needed. This valve works at 24V and connects with 3/4" sweat fittings. It controls hot and cold water in HVAC systems. The valve works better because it stays closed except when someone turns it on. The valve does three essential things, it helps systems work better, saves energy expenses, and works with many different fluids, such as water and glycol mixtures, for both home and commercial use.
