Electric flange butterfly valve

Electric flange butterfly valveButterfly valve: also known as butterfly valve.

Definition: The opening and closing component is a disc-shaped butterfly valve that can rotate around the axis of the valve body.

Structure: Mainly composed of valve body, valve stem, butterfly plate, and sealing ring. The valve body is cylindrical in shape, with a short axial length and a built-in butterfly plate.

Working principle: The butterfly plate is driven by the valve stem, and if it rotates 90 degrees, it can complete one opening and closing. By changing the deflection angle of the butterfly plate, the flow rate of the medium can be controlled.

Electric flange butterfly valveOperating conditions and media:

Butterfly valves are suitable for pipelines transporting various corrosive and non corrosive fluid media in engineering systems such as furnaces, coal gas, natural gas, liquefied petroleum gas, urban gas, cold and hot air, chemical smelting and power generation environmental protection, building water supply and drainage, etc. They are used to regulate and cut off the flow of media.

Advantages of electric butterfly valve:

1. Each product is subjected to pressure testing by Pande intelligent testing equipment, and an inspection report is automatically generated. Each data and report is saved for 5 years to ensure the factory pass rate. 2. The valve body and plate are made of QT450-10 material, with a spheroidization rate of grade 3 or above, a tensile strength of 450Mpa, an elongation rate greater than 10%, and are not easily cracked or frozen. 3. The valve body is a solid body and weighs more than other manufacturers with the same diameter. 4. The valve seat rubber uses EPDM rubber that meets the standard, and the rebound and tension of the butterfly valve are more stable and reliable, with no leakage after opening and closing more than 10000 times.
