ABSTRACT:
A valve made up of a body and a sleeve telescopically received in the body. A hand wheel is concentrically received on the sleeve and threadably received on the body for moving the sleeve axially of the body. A seal is provided in the body between the body and the sleeve. The seal closes the flow passage between the body and the sleeve when the sleeve is moved to one extreme position and opens the flow passage when the sleeve is moved to another extreme position. The sleeve is noncircular so that it will not rotate relative to the body. The valve is suitable for use on hot water tanks and the like for closing off the flow of water. The body has axially extending hooks that engage the body when the seal is moved to the open position so that the relative movement of the sleeve and body are limited and the sleeve and body will not separate.
