Mixing valves for DHW

Mixing valves for TV are thermostatic control devices used in hot water systems to blend hot and cold water and maintain a stable output temperature. These valves are commonly installed in domestic and commercial hot water circuits, such as in showers, sanitary fixtures, and service hot water systems, to ensure safe and consistent water temperatures. The category includes valves with fixed or adjustable temperature settings, varying flow capacities (Kv values), and different connection types and sizes to suit specific system requirements.

How to choose

• Select the appropriate connection type (internal or external thread) and nominal size (e.g., 1/2", 3/4", or 1") based on the pipe system design.
• Match the valve’s maximum operating temperature (e.g., +85°C or +90°C) to the system’s hot water supply conditions.
• Consider the required flow capacity (Kv value) to ensure the valve can handle the expected water flow rate in the circuit.
• Choose between fixed-temperature models (e.g., IVAR.MIX T0 for +50°C) or adjustable models (e.g., IVAR.C 521 for +30°C to +65°C) depending on the application’s flexibility needs.
• Ensure compatibility with system materials and pressure ratings (e.g., PN 10 or PN 14) for long-term reliability.

Frequently asked questions

Can thermostatic mixing valves for TV be adjusted after installation?
Some models, such as IVAR.C 521 and IVAR.MIX T5, allow for continuous temperature adjustment within a specified range. Others, like IVAR.MIX T0, are factory-set and cannot be changed.

What is the difference between internal and external thread connections?
Internal thread (F) valves have female threads for connecting to male pipe fittings, while external thread (M) valves have male threads for connecting to female fittings. This affects how the valve is integrated into the system layout.
