The valve is no leakage in both direction in shut off position. When
installing, leave the butterfly valve partly open. Make sure there is enough
distance between pipeline flanges to place the valve. Don’t add sealing
gaskets between the flange and the valve.
Insert bolts into flange and tighten opposing nuts sequentially. Make sure
that valve is aligned with the flange.
Fully open the valve. Make sure that the disc is centered and there is no
jam between the valve and the disc.
Pipeline flange standard should be consistent with the butterfly valve
flange standard. Make sure that the pipeline flange has enough surface
for sealing. It is necessary to ensure that the butterfly valve plate does not
collide with the inner diameter of the pipe during the opening process.
Avoid oil and impurity in the pipeline.
The butterfly valve must not be installed at the corner of the pipeline.
Don’t use the valve as a tool to increase the space between the pipeline
flanges.
The installation and commissioning of the valve actuator are completed
in the factory. Commissioning and dismounting should not be done on
site.
Connect the terminal according to the terminal number as shown on the
wiring diagram.

阀门为双向密封结构。安装阀门时，蝶板应处于接近全关的位置。确定
管道法兰间有足够的距离将阀门插入法兰中间。蝶阀安装时无须再加密
封垫,蝶阀端面自带软密封面。
将螺栓穿入法兰盘，用手或扳手对称轮流预紧螺栓，以法兰盘端面凸台
或外圆及阀体外圆为相互参照物，确认阀门是否与法兰盘对中。
谨慎地，轻轻地将阀门开启到全开位置，检查阀板是否对中，检查阀板
与法兰内孔有无磕碰现象。
管道对夹法兰标准需与蝶阀法兰标准相符，管道法兰端面与蝶阀软密封
端面需保证足够的接触面积用于密封，需保证蝶板在开启过程中与管路
法兰内径无磕碰。
管道内避免含有油及杂质。
蝶阀不得安装于管道拐角处。
不得使用阀门做撬杠，撬撑法兰。
阀门的驱动装置在出厂前已经安装调试完成，现场不得对其调试拆装。
按照接线图所示的端子号进行端子连接。
电动蝶阀若安装在室外，建议加装防雨水的防护罩
Recommend to install a protective cover against rain, if the motorized
butterfly valve is installed outdoors.
