Thermostatic mixing valve for safety showers

Article no.: BR 710 950

The thermostatic mixing valves of the ComfortLine series are special mixing valves for eye showers and safety showers that ensure highly precise control of the water temperature and scald protection. A continuous supply of hot and cold water is required for this purpose. The thermostatic mixing valves guarantee that the correct water temperature is always available at the tapping point and that unwanted temperature fluctuations are prevented.

Product description

The scald protection reliably protects the user from scalding. The scald protection comes into play when an uncontrolled overshoot of the hot water temperature occurs or the cold water supply fails.

The thermostatic mixing valve ensures continuous water supply even if the hot water supply fails (e.g. if the hot water is turned off). The function is used when the differential pressure between cold and hot water exceeds 0.5 bar. In this case, cold water escapes at the tapping point (bypass function).
