ABSTRACT:
A valve having a rotary valve head with an elastomeric seal attached to the valve head for use in a conduit is disclosed. Separate embodiments for use in a downhole tool and in an accessible surface valve are disclosed. An axially movable actuator tube is engagable with the elastomeric seal to maintain sealing integrity. A valve head with an integrally mounted seal can be actuated by an axially movable camming member or by a lever pivoting about an axis transverse to the conduit. Rotation of the valve head from the closed position aligns a flow passage with the conduit to permit fluid flow.
