Valve Flap, Pfeiffer, UNO, DUO, Part# 192348
valve flap like a small, flexible door inside your pump. It opens and closes at just the right times to let gas flow in one direction. When the gas tries to flow back the wrong way, the flap closes. This is called “regulating the flow” .
Without a good valve flap, your pump cannot move gas properly. The vacuum pressure drops. The pump has to work much harder. And your results can suffer.
If you use your vacuum pump for important jobs like:
Drying samples
Distillation
Filtration
Or any lab or industrial process
Then you need stable, reliable vacuum pressure. A worn or damaged valve flap can ruin that stability.
