-->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWith Centerline Butterfly Valves only two parts of the valve come in contact with the medium. This means that neither the body nor mechanical parts such as the shaft are exposed to the corrosive environment.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe only two parts in contact with the medium are the body lining and the disc. These are available in a selection of materials so that a suitable corrosion-resistant combination can be chosen for most any application.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Bi-directional Shutoff<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCenterline Butterfly Valves are liquid and gas-tight in both flow directions. The disc presses with uniform compression into the elastic cartridge seat over the entire circumference of the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Replaceable Seat<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe replaceable seat consists of a reinforced backup ring, on which the elastomer seat material is vulcanized. When mounting the valve between the pipe flanges this stable seat cannot be deformed or displaced. The cartridge design also prevents deformation when the valve is cycled, such as stretching and bulging of the elastomer in front of the moving disc.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe fixed connection between the elastomer and the backup ring allows the use of the valve in a full vacuum and high flow velocities. The slightly protruding sealing lip of the seat also serves as the flange seal.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-features-of-centerline-butterfly-valve\">Features of Centerline Butterfly Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Suitable for both gaseous and liquid service<\/li>\r\n \t<li>Phenolic Backed Seat for superior sealing and long term use<\/li>\r\n \t<li>Single-piece stem design assures even torque distribution<\/li>\r\n \t<li>Positive shutoff bi-directionally<\/li>\r\n \t<li>Direct mount automation<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Applications of Centerline Butterfly Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>HVAC<\/li>\r\n \t<li>Chemical\/Petrochemical Processing<\/li>\r\n \t<li>Food and Beverage<\/li>\r\n \t<li>Power and Utilities<\/li>\r\n \t<li>Pulp and Paper<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->","parent":0,"count":12,"filter":"raw"},{"term_id":3192,"name":"China EPDM Butterfly Valve","slug":"china-epdm-butterfly-valve","term_group":0,"term_taxonomy_id":3192,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_d933f8-47\"} \/-->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-what-is-epdm-butterfly-valve\">What is EPDM Butterfly Valve?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nEPDM is the abbreviated name for Ethylene Propylene Diene Monomer.

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.
