Calefactio is expanding its line of ball valves with high-flow drain with the addition of new NPT models, as well as new 2″ models, now available in all three connection types: Sweat, Press and NPT.
Calefactio’s new full port brass ball valves with high flow drain make it easy to quickly isolate and drain any section of the system, simplifying maintenance and service work. A new integrated tag indicating flow direction, combined with a 270° rotating handle, makes draining from either side easier and improves field usability.
Thanks to their compact full-port design, these valves promote optimal flow while reducing the risk of pressure drops and debris buildup. Rotating the handle efficiently redirects flow from the main channel to the drain, while avoiding the reduced-port alternatives commonly used on the market.
Made of forged brass and equipped with a high-flow drain, these valves are available with Sweat, Press and NPT connections, in sizes ranging from ¾” to 2″, to suit a wide range of plumbing and hydronic heating applications.
