Thermostatic mixing valve for eye showers

Article no.: BR 710 940

The thermostatic mixing valves of the ComfortLine series are special mixing valves for eye showers and safety showers that require highly precise control of the water temperature, scald protection and continuous access to water. The thermostatic mixing valves ensure that the correct water temperature always prevails at the point of use 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).

Technical Description

  • Adjustment range 20-40°C, preadjusted to 22°C
  • automatic testing of the cold and hot water supply
  • Hidden water temperature setting with scald protection at 40°C
  • safety switch-off of the hot water in case of failure of the cold water supply
  • Flow rate 20 litres / minute at 1 bar flow pressure
  • Hot water connection 1/2” male, cold water connection 1/2” male, water outlet 1/2” male
  • Integrated backflow preventer in cold/hot water connection to protect the drinking water
  • Abmessungen (H x B x T): 136 x 130 x 46 mm
  • according to BGI/GUV-I 850-0, DIN 1988 and EN 1717
  • according to ANSI Z358.1-2014 and EN 15154-2:2006
  • Manufacturer: B-SAFETY or equal
