Bellows Seal Valve Installation Tips
|
Always follow standard safety procedures when working on a valve. Bellows seal valves provide a complete hermetic seal of the working fluid. They are used in applications where zero leakage of the working fluid into the environment is permitted. Bellows seal valves are specially modified versions of the standard valves. The installation information that applies to gate and globe valves will apply to bellows seal valves. A packing leak signifies that the bellows has ruptured or the bellows-assembly weld has a crack. Velan does not recommend repairing or reusing a damaged bellows. Instead, Velan suggests replacing the entire bonnet assembly including bellows and stem.
