Abstract
A check valve includes a valve body having a flow bore which extends between the inlet and outlet ends of the body, a cavity which intersects the flow bore, and an opening which is connected to the cavity. A body cap is removably secured in the opening, and a seat cartridge is configured to fit through the opening and be slidably received in the cavity. The seat cartridge has an open first end which is aligned with the opening, a second end which is located opposite the first end, a chamber which extends between the first and second ends and defines an inner wall of the seat cartridge, a first bore which extends between the chamber and an inlet bore portion, a second bore which extends between the chamber and an outlet bore portion, and a valve seat which is formed on a portion of the inner wall that surrounds the first bore. A retainer ring is positioned in the valve body between the body cap and the first end of the seat cartridge, and a flapper is pivotally connected to the retainer ring and is pivotable through the chamber between a closed position in which the flapper is positioned against the valve seat and an open position in which the flapper is displaced from the valve seat.
