Abstract
A valve for connection to a pressurized gas cylinder 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 comprising polyetherimide or polyaryletherketone.
