Thermostatic Mixing Valves (Large Bore)

A range of DN32, DN40 and DN50 Horne thermostatic mixing valves that provide temperature control for larger dead-leg mixing applications or circulating domestic hot water systems (DHWS), and for circulating systems in conjunction with water treatment, such as ionisation.

Features and benefits:

• Four temperature ranges* available: 15°C - 32°C (T1), 32°C - 52°C (T2), 45°C - 62°C (T3), 58°C - 80°C (T4).
• Highly accurate temperature control across full range of flow rates.
• Mixed water temperature accurately and reliably controlled over full range of flow rates - from all outlets in use simultaneously, to only one outlet in use (dead-leg applications). Supply pressures should be nominally equal.
• Mixed water temperature maintained when no outlets are in use. See 'Circulator Location' best practice advice below.
• Water at the desired temperature is always available at every outlet.
• Supplied as an assembled package.
• Easily installed on site.
• Ease of maintenance.
• Easily stripped and cleaned without the need for special skills or tools.
• Robust and reliable.
• UK Water Regulation 4 compliant.

* Append the relevant range code (e.g., T1) to your selected product variant, such as H40-RT4. Also note - If the intended output set temperature falls within more than one range (e.g., 60°C), choose the range where the set point is closer to the lower limit, thus T4. This reduces expansion fatigue on the thermostatic element, extending its operational life.
