Abstract

See full text

Check valve inserts define a valve seat for an open position of a check valve and have an outer support seatable in an internal chamber of the check valve and have an inner annular ring spaced radially inward from the outer support by a rib that angles axially toward a central longitudinal axis to position an upper surface of the inner annular ring a distance axially beyond an upper surface of the outer support. Check valves have a housing defining an inlet port, an outlet port, and a chamber in fluid communication with the inlet and outlet ports, have the check valve insert seated with the chamber, and have a seal disc moveable within the chamber between the open position defined by the inner annular ring of the check valve insert and a closed position. The seal disc is translatable in response to a pressure difference across the seal disc.
