Float Valve Duo & Smart 5 & 6 Quart
This float valve is designed for the Duo 5 and 6 quart, and Smart 6 quart. It does not fit other models.
The float valve is designed to be pushed up once there is sufficient pressure inside the Instant Pot. Once pushed up, the silicone band seals the cooker and the pin of the float valve serves as a latch lock, preventing the lid from being accidentally opened.
