Abstract
A valve is disclosed. The valve has a housing that defines a central area and has at least two flow ports therethrough. A cover is provided that has a flapper assembly pivotally attached thereto. The cover is removably attachable to the housing in a plurality of orientations to selectively orient the flapper assembly adjacent any one of the ports such that fluid is permitted to flow into the central area of the housing through the adjacent port. The flapper assembly prevents the fluid from flowing back out of the central area through the adjacent port. The cover may have a transparent portion to permit the flapper assembly to be viewed and inspected during operation. A double seal arrangement is also disclosed.
