The duckbill valve is the small silicone part that creates the vacuum and directs the milk flow in the right direction. It's what makes pumping work, and it's also the first part to check when suction weakens.
Made from soft, food-grade silicone, BPA-free. It's designed to wear out, which is normal, it's its job. Anticipate replacement rather than suffering a drop in efficiency.

Signs: unexplained loss of suction power, deformed valve, visible cracks, or a valve that no longer stays in place in the connector.
When in doubt, replace it; it's often the culprit when the draw loses effectiveness.
Wash with hot soapy water after each pumping session, or steam sterilize. Do not use sharp utensils to clean, as this would damage the silicone and render the valve unusable.
Yes, before first use.
Afterward, washing them with hot water and mild soap after each use is sufficient.
You can sterilize them occasionally if you wish.
