The 521 MixCal™, 5213 and 5231 Series adjustable thermostatic mixing valves are used in residential and commercial systems producing domestic hot water or in hydronic and radiant heating systems. Compensating for both temperature and pressure fluctuations of incoming hot and cold water in point of distribution or point of use (scald protection) applications, these low-lead certified valves maintain the desired output temperature of the mixed water, delivering comfortable heat and ensuring customer satisfaction.
An optional outlet temperature gauge accurately confirms the mixed temperature for the 521 and 5231 valves. Check valves in inlet hot and cold ports are optional for the 521 and 5231 and standard for the 5213. Popular Presscon™ fittings, designed for installation ease, are available for the 521. The 521 and 5231 are certified to ASSE1017. The 5213 to ASSE 1070.
