The integrated union makes maintenance easier, while the built-in drain simplifies tank draining. The valve is also equipped with a lockable handle that can be secured with a padlock, as well as a pressure gauge port. By reducing the number of joints and fittings required, it directly helps minimize the risk of leaks while providing a cleaner, more reliable, and longer-lasting installation.
Every additional fitting means more time on the job site, higher labor costs, and greater potential for leaks over time. By integrating multiple functions into one compact unit, the Calefactio service valve with union significantly reduces assembly time and simplifies the installer’s work.
Fewer fittings also mean less maintenance time. The integrated union allows components to be removed or replaced without dismantling the entire piping system, making servicing much faster and more efficient. Its compact format also helps optimize space in installations where every inch matters.
Made from lead-free forged brass, this valve combines durability, reliability, and ease of installation. Available with ¾˝ to 1½˝ NPT connections.
With this new solution, Calefactio helps professionals save time, reduce installation costs, and minimize the risk of leaks right from the start.
