Abstract
A swing check valve, which is adapted for automatically inhibiting back flow of fluid from an outlet thereof to an inlet thereof, includes a clapper member and a housing. The housing has a first body portion, which includes its own valve seat and its own mounting mechanism adapted to removably mount the clapper member therefrom when the first body portion is positioned adjacent to the inlet of the valve. The housing also has a second body portion, which includes its own valve seat and its own mounting mechanism adapted to removably mount the clapper member therefrom when the second body portion is positioned adjacent to the inlet of the valve. The first and second body portions are removably connected to each other in an end-to-end fashion and are interchangeable with each other, whereby each body portion may be utilized as a replacement for the other body portion.
