Domestic water applications, particularly in North America, are challenging because our water can be very hard (have a high mineral content) compared to Europe. Our colleagues across the water remind us of this regularly! Fortunately, the 521 and 5231 Series mixing valves are designed to stand up to our tough water conditions!
Caleffi 521 Series and 5231 Series TMVs are high quality, high performance valves that can be used in either hydronic or plumbing applications. Because most of the valve is made of low lead brass, they meet the Reduction of Lead in Drinking Water Act, are ASSE and CSA approved, and are very popular for use in plumbing applications across North America.
Whenever hard water is heated, limescale deposits form which can have an adverse effect on moving parts and piping in general. That, and other forms of dirt and corrosion, can cause any mixing valve performance to suffer if allowed to get out of hand. The good news is our valves can easily be cleaned.
