Claim 9

A valve construction comprising a body section, a handle member, means for rotatably and sealingly mounting said handle member on said body section, means for restraining said handle member against axial movement relative to said body section, a floating valve stem mounted within said body section for movement toward and away from a valve seat thereof, means for restraining said valve stem against rotation relative to said body section, and cooperative means on said handle and on said valve stem for translating rotary movement of said handle member into axial movement of said valve stem toward and away from said valve seat, said handle restraining means including an outwardly extending peripheral flange formed on said body section and resilient axially extending lugs formed on said handle member for engagement with said flange.

Claim 10

The combination according to claim 5 wherein said lugs are provided with inwardly extending snap over tabs, said tabs being chamferred to provide camming surfaces to facilitate their snapping over said flange.

Claim 11

In a valve construction, the combination comprising a body section, a handle member, means for rotatably and sealingly mounting said handle member on said body portion, a conduit means fitting mounted solely on said handle member, and means including a rotating seal mechanism on said fitting and on said handle member for rotatably and sealingly mounting said handle fitting on said handle member for rotation relative to said handle member whereby translation of handle-turning motions to the conduit means is avoided and wherein said handle member is provided with a skirt portion closely fitted about said body section and said mounting means include an O-ring seated in groove means formed on at least one of said body section and said skirt.
