Air/water valve
Suction valve
Skirt
Suction cylinder
The air/water valve may stick at first, but it should operate
smoothly after it is depressed a few times.
If a biopsy valve is not properly connected to the instrument
channel port, it can reduce the efficacy of the endoscope's
suction system, and leak or spray patient debris, posing an
infection control risk.
