The butterfly plate of the rubber-lined butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of sanitary butterfly valve body, disc-shaped butterfly plate rotates around the axis. Its rotation angle is between 0 and 90 degrees. When the rotation angle reaches 90 degrees, the butterfly valve is in fully open state. This type of rubber-lined butterfly valve should generally be horizontally installed in the pipeline.
Rubber-lined butterfly valve product is comprised of rubber sealing butterfly valve and carbon steel, stainless steel valve plate and valve stem. Electric rubber-lined butterfly valve is suitable to be used in water supply and gas pipelines of food, medicine, chemicals, petroleum, electricity, textile, paper industries where the temperature is between 80 and 120 degrees Celsius to regulate the flow and shut off the medium.
The structural features of electric rubber-lined butterfly valve:
1. The design is novel and reasonable. The structure is unique. The weight is light. The opening and closing is quick.
2. The operating torque is small. It’s easy, effortless and flexible to operate.
3. It can be installed in any position. Easy maintenance.
4. The sealing member can be replaced. The sealing performance is so reliable it can achieve two-way sealing with zero leakage.
5. The sealing material is aging-resistant, weak-corrosion-resistant, with a long service life.
