LV electric seal butterfly valve/electric seal door is around 90 ° with disc type opening and closing a reciprocating rotary to open and close the fluid channel of a valve. Butterfly valve is not only simple structure, small volume, light weight, material consumption, installation size is small, and the drive torque, easy operation, fast, and closed but also at the same time has good sealing performance. The electric door has a very wide range of use. Continues to expand its use varieties and quantity, and to high temperature and high pressure, large diameter, high sealing, long life, good adjusting performance, reliability and other performance indicators have reached a higher level, and has set up a part replace the cut-off valve, gate valve and ball valve. Especially suitable for large caliber, the use of low pressure area,

Opening and closing butterfly valve is suitable for the flow. Because of the butterfly valve in the pipeline pressure loss is bigger, about three times the gate valve, so when choosing butterfly valves, piping system is affected by pressure loss should be considered, also should consider closing butterfly plate consistence of pipeline medium under pressure. In addition, you must consider resilient seat materials at high temperature on the operating temperature limit.

The structure of the butterfly valve length and smaller overall height, opening and closing speed, and has good flow control characteristics, the structure principle of butterfly valve is most suitable for making big through the valve. When the butterfly valve for control flow using one of the most important correct choose the size and type of butterfly valve, and making it work properly and effectively.

Product features:

1, the new design, reasonable, unique structure, light weight;

2, easy to operate, drive torque, opening and closing rapidly, and effort;

3, the products are widely used in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food and beverage industry, environment protection, building materials, electricity, glass and other ventilation environmental protection, as the dust of cold or hot gas cut off or adjust flow;

4, using high-tech materials, meet the low, medium and high temperature gas and contain different degree of corrosion medium;

5, the type of valve plate material after heat treatment, its applicable temperature range is very wide, can guarantee to 40 ℃ ~ 1200 ℃ within the scope of use;

6, adopt new technology of sealing structure, heat leakage rate of 0.5% or less, under the normal temperature of zero leakage rate;

7, interface diameter is large, can reach DN4000mm.
