A pneumatic bellows valve is a vacuum or process-gas hardware component used to route, isolate, adapt, or seal gas/vacuum paths.
Correct valve and fitting selection is important for leak integrity, process cleanliness, and safe tool operation.
Stainless steel, aluminum, elastomer seals, or vendor-specific wetted materials may be used depending on the exact assembly.
Vacuum fittings and valves rely on compatible sealing faces, gaskets, and actuator/control interfaces.
