Determination of the size of the MIXING VALVE

How to determine the parameters

  • Displayed Temperature on mixing valve : 38°C, 45°C ou 50°C
  • Type of Installation : you have 3 choice where the decrease coefficients of flow rates K (simultaneity coefficients) are different according the usage of the site :
    - Living accommodation.
    - Collective accommodation, Multiple showers (Hotel, Camping, Hospital, Hydrotherapy).
    - Various : Stadium, Gymnasium, Factory, School, Swimming pool, Barracks.
  • Inlet pressure :
    0.5 bar at 3 bar.
  • You only have to enter the number of appliances to be supplied with mixed water.
    Click on the option buttons in front of the appliances and put the correct value in.
  • Click on the button Calculate the mixing valve for obtaining the result of the calculation and the selection of the mixing valve’s size corresponding to your case.

You can discover the following results :

  • The total quantity of appliances
    (that will be used for calculating the coefficient of simultaneity)
  • The gross flow rate in litters per minute
  • The coefficient of combined flow
  • The likely flow rate in litters per minute
  • The selected mixing valves and its complete characteristics.
