    • 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.
    • 公开了一种用于连接到加压气瓶的阀。 阀包括壳体,其包括可连接到气瓶的气瓶孔,以及壳体导管,其从气缸孔延伸穿过壳体到一个或多个入口/出口孔,使得阀能够提供流体连通 在通过壳体导管的气瓶和一个或多个入口/出口孔之间。 壳体导管内的流动控制球可在打开位置和关闭位置之间移动。 球形密封件具有对应于流量控制球的形状的密封表面,用于基本上密封壳体管道中的流动控制球。 其他特征包括通过一个入口/出口孔安装球形密封件的部件; 用于将杆安装到包括轴承的流动控制球的部件; 活港口 可从外壳的其余部分可拆卸地连接的管; 在阀门壳体中接收EFV和/或PRD的规定; 并且球形密封件和杆轴承中的至少一个由包括聚醚酰亚胺或聚芳醚酮的特殊聚合材料构成。
