A bellows valve comprises a main body defining a valve chamber including a valve seat having inlet and an outlet passages connected therewith. A vlave element is positioned in the chamber and has an operating stem with a free end extending axially therefrom. An actuating assembly for moving the valve element toward and away from the seat, includes a rotatably mounted actuating shaft having a free end axially aligned with the free end of the operating stem and an operator for selectively producing axial movement of the actuating shaft. The operating stem is joined to the actuating shaft by a connection including a first ball member positioned axially between the free ends of the operating stem and the actuating shaft with a spring engaged with the first ball member and acting to bias the free ends of the operating stem and actuating shaft axially apart. A plurality of second ball members interconnect the stem and shaft for preventing axial separation of the free ends while permitting free relative rotation.
