Abstract
A tap valve selectively taps a line while maintaining fluid continuity within the line. The valve comprises a throughput tube and a tapping port which terminates at a rotatable member. The rotatable member has a generally circular cross section and may be oriented either to provide fluid communication between the throughput tube and tapping port or to seal off the tapping port.
