Abstract
A ball check valve assembly for assuring unidirectional flow through a meter run. The valve assembly includes a plate member adapted to be placed between the confronting flanges of a pipeline or meter run and positioned so that back flow cannot occur back through the meter run. A passageway formed through the plate member extends into an enclosure which has a valve seat formed on the top wall surface thereof through which unidirectional flow can occur. One wall surface of the enclosure extends up and then bends towards the plate member. The marginal free end of the bent part of the back plate member is apertured to admit the ball to be received therein, thereby capturing the ball between the seat and aperture in a manner that enables the ball always to gravitate back into sealed relationship respective to the seat, and yet the ball can be displaced sufficiently far enough from the seat to achieve relatively unobstructed flow.
