In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The \"butterfly\" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid.

They are open and close very quickly when actuated pneumatically. The disc is lighter than a ball, and the valves require less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list {\"ordered\":true} -->\r\n<ol>\r\n \t<li>Turning on\/off easily and rapidly with less force. Having less fluid resistance and can be operated frequently.<\/li>\r\n \t<li>Simple structure, small size, and short face-to-face dimension, which are suitable for large-diameter valves.<\/li>\r\n \t<li>It can be used for transmitting mud, fewer liquids are stored at the apertures of the pipe.<\/li>\r\n \t<li>Long service life. Standing the test of tens of thousands of opening\/closing operations.<\/li>\r\n \t<li>Butterfly valves have excellent regulation performance.<\/li>\r\n \t<li>Small torque. The pressure on discs at the two sides of the spindle is almost equal, causing contrary torque. Thereby, the valves can be opened with less force.<\/li>\r\n \t<li>A sealing face is generally made of rubber or plastic. So the butterfly valves can be with good sealing under low pressure.<\/li>\r\n<\/ol>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>EPDM Butterfly Valve - China Manufacturers, Factory, Suppliers<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWe'll make each hard work to become excellent and excellent, and speed up our measures for standing from the rank of intercontinental top-grade and high-tech enterprises for Epdm Butterfly Valve, Rubber Lined Double Flange Butterfly Valve, Butterfly Valve Wafer, Electric Actuator Butterfly Valve, Lug Support Butterfly Valve.
