Thermostatic mixing valve for boiler protection against acid corrosion.
Acting temperature: 130°F - 55°C
Protect boiler inner wall from condensation. The exhaust gas will condensate in acid water when the heating return is less than 130°F. Acid water on the inner wall will reduce greatly the boiler lifetime.
