Original Abstract Submitted
A swing check valve includes a valve body that defines a fluid flow path from a fluid inlet to a fluid outlet; a flapper coupled to the valve body and moveable between a first position to allow fluid flow in a primary flow direction through the fluid flow path and a second position to impede fluid flow in a secondary flow direction through the fluid flow path; a seat coupled to or integral with the valve body within the fluid flow path such that the flapper is apart from a face of the seat in the first position and abuts the face of the seat in the second position, the seat including a groove formed in the face; and a dampening ring positioned within the groove and including an interface aligned with the face of the seat such that the flapper abuts the interface in the second position.
