Buitink Technology designs, develops 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

• Maximum local temperature 70 degrees Celsius.
• Emission should be water vapor with low concentrations of chlorides and grease.
• Pressure applied to the balloon does not exceed 1 bar.
• In an emergency situation the chimney must be immediately fully operational, so the balloon must occupy little volume when empty.
