Abstract:

Fluid apparatus and related methods are disclosed. An example fluid apparatus includes a body defining a fluid flow path between an inlet and an outlet. A flow control member is positioned in the fluid flow path. The flow control member has a base pivotally coupled to an inner wall of the body defining the fluid flow path. The flow control member has an annular tip that is to flex between an open position to allow fluid flow through the fluid flow path and a closed position to prevent fluid flow through the fluid flow path.
