butterfly valve design provides a viable and economical alternative to the gate valve for many high vacuum applications. Unlike other manufacturer’s butterfly valves that use only a throttle plate to limit the conductance through the opening of the valve, Huntington’s design provides a vacuum tight O-ring seal. The new design allows the sealing plate to “float” within the valve orifice so that in closing it centers itself with even pressure around the O-ring seal. This design reduces scuffing or rolling of the O-ring. 蝶阀设计为许多高真空应用提供了一种可行且经济的闸阀替代方案。与其他制造商的蝶阀不同，后者只使用节流板来限制通过阀门开口的传导，亨廷顿的设计提供了真空密封的O形密封圈。新的设计允许密封板在阀孔内“浮动”，这样在关闭时，它会在O形密封圈周围均匀的压力下居中。这种设计减少了O形环的磨损或滚动。
