Valves for the safe closing of fireplaces

Buitink Technology designes, developes and produces custom made (inflatable) applications. By default it is based on a specific and challenging problem, where usually no standard solution is available.

Inflatable ball valve

A typical example is an inflatable ball valve, developed by Buitink Technology, to close a chimney.


A chimney, out of order in a regular process; the input to the chimney is closed down through valves. Usually these "simple" valves have a leakage. To prevent the leakage flow passing the chimney an inflatable ball valve is applied.

Properties/boundary conditions of the valve

  • Maximun local temperature 70 degrees Celcius.
  • Emission should be water vapor with low concentrations of chlorides and grease.
  • Pressure applied to the balloon does not exeed 1 bar.
  • In an emergy situation the chimney must be immediately fully operational. The de-flated valve therefore has a small volume generating no obstruction in the chimney pipe.
