Jiangsu Lan adopted IS09001-2008 quality system certification butterfly price, the product passed the national certification explosion-proof electrical product quality supervision and inspection center, made explosion-proof certificate and coal safety certificate. 1 ball advantage. Fluid resistance, ball full bore little flow resistance. 2. Simple structure, small size and light weight. 3. Compact and reliable. It has two sealing surface, and valve sealing surface material widely used kinds of plastic, sealing, and can be completely sealed. In the vacuum system it has also been widely used. 4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as 90 ° rotation of butterfly effect, to facilitate remote control. 5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient. 6. In the fully open or fully closed, sealing surface and the dielectric isolation ball and seat, valve manufacturers, will not cause erosion of the valve sealing surface through the media. 7. Wide range of applications, from small to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied. 8. Since the ball valve opening and closing process wiping, so can be used for media with suspended solid particles.
