摘要： A bellows valve construction which facilitates valve use at elevated temperatures and pressures. The valve includes a valve body having a passageway extending thereinto for defining a valve chamber with a valve seat disposed along this passageway and a fluid inlet and a fluid outlet communicating therewith on opposite sides of the seat. A bonnet is integrally associated with the valve body and includes a bonnet opening coaxial with the valve body passageway. A valve assembly is receivable as a unit in the bonnet opening with a portion thereof extending into the valve chamber for selectively controlling fluid flow between the fluid inlet and outlet. This valve assembly is removable from the valve body as a unit for repair or replacement purposes and includes an adapter nut threadedly receivable in the bonnet opening, a valve member, an elongated stem, and a hollow bellows passing through the bonnet opening in a surrounding relationship with at least a portion of the stem. One end of the bellow is affixed to the adapter nut with the other end being affixed adjacent the valve member such that fluid passing through the valve exerts a compressive force against the bellows. A first urging means is adapted to selectively move the valve stem and member into a valve opened condition and a second urging means is adapted to move the valve stem and member into a valve closed condition. The valve is adapted for either manual or remote operation.
