Disc, the trim part of butterfly valves, rotates with the stem to open/close and modulate the valve.
蝶阀是随阀杆一起转动的蝶板作启闭件，用以实现阀门的开启，关闭与调节。
A butterfly isolation valve cannot be installed directly to the valve inlet flange, as the disc will contact the orifice plate.
蝶阀隔离阀不能够直接安装在阀门进口法兰上，因为其阀瓣将会接触到节流板。
Check valve and butterfly valve combinations are very popular; normally a short spool piece is required between the valves.
止回阀与蝶阀的连接是经常发生的事,通常需要在这两种阀门之间加上一节短短的阀槽。
Stem extensions can be furnished to permit remote operation of butterfly valves in any required length.
配备所需长度的阀杆延长件,可以对某个蝶阀进行远程操作。
Grooved butterfly valves direct connect to pipe using iron pipe size couplings. Grooved valves are easiest to install.
管状蝶阀:采用铸铁管接头直接与管道连接。管状阀门安装最容易。
