The flow coefficient adjustment butterfly valve of the analysis and regulation butterfly valve is also called the ventilation butterfly valve, which belongs to a kind of butterfly valve. It is mainly used for gas pipeline systems in metallurgy, mining, cement, chemical industry and power generation industries as flow regulating equipment. The valve is mainly composed of valve body, valve disc and driving device. Its basic principle is that the drive device drives the valve plate to open at any angle between 0~90 °, so as to control the flow of medium in the pipeline when flowing through the valve body

Main performance of explosion-proof pneumatic butterfly valve
The explosion-proof pneumatic butterfly valve is woven with imported high-quality 304 stainless steel wire, which has the advantages of high strength and corrosion resistance. After fine processing, it has the advantages of uniform appearance, no jumping, overlapping and breaking. The connecting nuts at both ends of the hose are forged with high quality H59 copper, and the rubber gasket (sealing ring) is made of high quality Buna N rubber or EPDM rubber. After many severe tests, its sealing performance is outstanding. The connecting nut is equipped with various specifications, which makes the device and connection easy. The inner tube is made of high-quality ethylene propylene diene monomer (EPDM) imported from the United States. Its anti-aging, cold resistance, high temperature resistance and corrosion resistance are far higher than those of domestic materials. The preparation of the inner tube materials is made of American technology. The participating additives are stopped from strict scientific matching and control to ensure the non-toxic and environmental protection performance of the product. After the outer layer is braided, it has the characteristics of high pressure resistance and explosion-proof.
