美国尼伯科止回阀可以安装在水平管线和流向朝上的垂直管线的任何位置上。在角度不大于15o的倾斜管线上也能够令人满意的工作。
NIBCO check valves may be installed in both horizontal and vertical lines with upward flow or in any intermediate position. They will operate satisfactorily in a declining plane (no more than 15o).
警告：不要用在往复式空气压缩机管线上。
Warning – Do Not Use For Reciprocating Air Compressor Service.
