摘要

A flow control valve for use in oxygen systems. The flow control valve has a body within an inlet and an outlet. A seat is located within the body and a ball retainer is located within the body. The ball retainer is able to capture a ball. The flow control valve also has biasing means connected to the ball retainer. Furthermore, the biasing means is movable between a flow and a non-flow position. The ball retainer is in a closed position when the ball, captured by the ball retainer, engages the seat to prevent gas flowing through the seat.
