Abstract
The present invention relates to a valve member for a valve of the ball valve type, including two shell parts rigidly joined together to form a valve member and generally snap-fitted over a frame. The two shells have opposed sealing surfaces and a flow passage extends through the shells and the frame. The valve member includes a means for engagement of a drive mechanism to enable rotation of the valve assembly, wherein said valve member can be rotated to present a sealing surface or alternatively rotated to present a flow path to a water supply when said valve member is located in a sealed fluid passage such as a pipe.
