Examine valves have two ports and restrict the flow of fluids and other loose materials through a pipeline or passage to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two usual types of check valves are ball cone valves and swing check valves. A ball cone valve uses a spring-loaded ball seated versus a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Examine valves are ranked by their fracturing pressure (the minimum upstream pressure needed for the valve to run), and they are made use of in various water, gas, air, and steam lines.
