ABSTRACT:
A valve having a valve body, a valve cavity, a first opening and a second opening with a valve member rotatably positioned within the valve cavity. The valve member may have a generally cylindrical hollow configuration with an end opening in alignment with the first opening, and a side opening with the valve member positioned for rotation to bring the side opening into or out of alignment with the second opening. A seal means is supported by the valve member in slidable contact with the valve cavity with the seal means enclosing the end opening and side opening of the valve member.
The valve body may also include a valve member opening in alignment with the valve member. A removable closure member is positioned over the valve member opening. On removal of the closure member, the valve member may be removed from the valve cavity by withdrawing the valve member through the valve member opening.
The valve body may also include a third opening with rotation of the valve member providing flow communication between the first and second openings or between the first and third openings. The seal means may enclose the second and third openings when the side opening of the valve member is in communication with either of the second or third openings.
