中文品名：圆片型蝶阀，带涡轮

Compared with conventional gate and globe valves, butterfly valves achieve high performance near to perfection with its pressure resistance and durability.  Especially in vessels, the Butterfly Valves enjoy high reliability and when compared with the conventional valves, the Butterfly Valves are excellent in the following aspects: 

(1) light and compact

(2) maintenance is easy

(3) labour-saving ease of operation

(4) low cost

Worm Gear Actuator:  Gear reduction is available by the worm and worm wheels incorporated, opening the disc very lightly, leading to non-step adjustment of flow.  In addition, a stopper bolt is fitted to the fully closed and fully opened positions, hence accurate positions can be taken.  Furthermore, the opening angle of the disc can be read by the indicator at the upper part of the gear box.  "Close" is effected by revolving clockwise, and "Open" by revolving anticlockwise, with the manual handle.

与传统闸阀和截止阀相比，蝶阀的耐压性和耐久性达到了近乎完美的高性能。特别是在容器中，蝶阀具有很高的可靠性，与传统阀门相比，蝶阀在以下几个方面表现优异：
(1)轻便紧凑。
(2)维护方便。
(3)省力、易操作。
(4)成本低。
蜗轮传动装置：蜗杆和蜗轮配合减速，打开阀瓣非常轻微，导致流量无级调节。此外，在完全关闭和完全打开的位置都安装了止动螺栓，因此可以精确定位。此外，齿轮箱上部的指示器可以读取圆盘的打开角度。用手动手柄顺时针旋转“关闭”，逆时针旋转“打开”。
