摘要： A bellows valve comprises a main body (16) defining a valve chamber (18) including a valve seat (28) and having inlet and outlet passages (20, 22) connected therewith. A valve element (24) is positioned in the chamber (18) and has an operating stem (30) with a free end extending axially therefrom. An actuating assembly (14) for moving the valve element (24) towards and away from the seat (28), includes a rotatably mounted actuating shaft (58) having a free end axially aligned with the free end of the operating stem (30) and a handle (60) for producing axial movement of the actuating shaft (58). The operating stem (30) is joined to the actuating shaft (58) by a connection including a first ball (80) positioned axially between the free ends of the operating stem (30) and the actuating shaft (58) with a spring (86) engaged with the first ball (80) and acting to bias the free ends of the operating stem (30) and actuating shaft (58) axially apart. A plurality of second balls (94) interconnect the stem (30) and shaft (58) for preventing axial separation of the free ends while permitting free relative rotation therebetween.
