Lubrication and sealing of valves on hot air balloons

2009-03-27View Original

Thread Content

Lubrication and sealing of the valves in the propane supply system of hot air balloons: The operating temperature range is strictly from -40 to 100 degrees. At high altitudes, the temperature can drop to -40 degrees, while the temperature resulting from propane combustion can reach 100 degrees. It is therefore very important that the valves maintain good lubrication and sealing properties.
