Knife gate valve is a gate valve with a gate whose movement direction is perpendicular to the fluid direction as the opening and closing part. It has the function of cutting off the medium and is often used in some fluid pipelines that are difficult to control. According to the needs of field control, electric or pneumatic actuators are widely equipped to realize the automatic operation of the valve.

Knife gate valve is a gate valve with a gate whose movement direction is perpendicular to the fluid direction as the opening and closing part. It has the function of cutting off the medium, so that the valve can be closed without being blocked by the medium. The effect of cutting off the medium is good. It is often used in some fluid pipelines that are difficult to control. It is widely used in mining, food, papermaking, medicine, petroleum, chemical industry and other fields. The traditional knife gate valve is manual, but according to the needs of on-site control, Electric or pneumatic actuators are widely equipped to realize the automatic operation of valves.

The knife gate valve disc has the characteristics of simple assembly and maintenance, reasonable sealing structure, convenient replacement of sealing ring, convenient practical operation, free opening, flexible and reliable movement, etc. However, in order to prevent adverse effects of products during installation, the following points should be paid attention to:
1. Pay attention to keep the valve cavity and sealing surface clean, and avoid installation with dirt or sand attached;
2. Check whether the bolts at all connecting parts are tightened evenly to ensure that the valve pipeline falls off under the impact of the medium;
3. Check whether the packing part of the valve is compressed to ensure the tightness of the packing and the opening flexibility of the ram;
4. Check the valve model, connection size and medium flow direction to ensure that they are consistent with the requirements of the valve pipeline;
5. Reserve the necessary space for valve drive to facilitate operation;
6. If automatic driving device is adopted, check whether the wiring of the driving device is connected according to the circuit diagram;
7. The valve shall be maintained regularly to avoid collision and extrusion, so as to ensure the tightness of the valve.
