摘要： Disclosed is a valve for connection to a pressurized gas cylinder. The valve includes a housing including a gas cylinder aperture which is connectable to a gas cylinder, and a housing conduit which extends through the housing from the gas cylinder aperture to one or more inlet/outlet apertures so that the valve is capable of providing fluid communication between the gas cylinder through the housing conduit and the one or more inlet/outlet apertures. A flow control ball within the housing conduit is movable between open and closed positions. Ball seals have sealing surfaces corresponding to a shape of the flow control ball for substantially sealing the flow control ball in the housing conduit. Other features include components for mounting the ball seals though one of the inlet/outlet apertures; components for mounting a stem to the flow control ball including bearings; live ports; a tube which can be removably connectable from the rest of the housing; provision for receiving an EFV and/or a PRD in the valve housing; and at least one of the ball seals and stem bearings being comprised of special polymeric material including polyetherimide or polyaryletherketone.

摘要： The invention relates to a valve assembly which includes at least one, but typically two, balls located along a passage and which balls can be moved between open and closed positions to selectively control the passage of fluid along the passage. The valve assembly includes at at least one end thereof a retaining assembly which allows the effective sealing against one surface of a ball and retention of the same in position. A sealing assembly is also provided when two balls are provided, intermediate the same, which allows effective sealing to be achieved and at least one of the two trunnions which allows each of the balls to be mounted within the valve body is located only internally of the valve body. The components of the valve assembly which are located within the same can in one embodiment all be inserted into and located within the valve body from one common end.
