In this design of the valve, the stem crosses from the centerline of the disc. Between the pipe bore and the seat, there is the inside diameter boundary. This zero-offset valve is also called resilient-seated because it relies on the adaptability of the seat rubber to seal the flow after closing it efficiently. At around 85\u00b0 during a 90\u00b0 rotation, the disc first comes into connection with the seat in this kind of valve.

As the stem is positioned behind the centerline, the valve is called a single offset. This design helps to minimize the disc contact with the seal, which increases the service life of the valve. In double-offset butterfly valves or doubly eccentric butterfly valves, the stem is positioned at the backside of the disc with an extra offset. This stem design allows the rotating disc to cover the seat only for one to three degrees. A triple offset butterfly valve is frequently used in more complex applications that have the same design as a double offset butterfly valve. A triple offset butterfly valve is efficient and reduces wear. This valve has metal seats that create a bubble-tight shut-off and make it able to use in higher temperature applications.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":9,"filter":"raw"},{"term_id":1881,"name":"Butterfly Valve Wikipedia","slug":"butterfly-valve-wikipedia","term_group":0,"term_taxonomy_id":1881,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_49a87c-f7\"} \/-->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-what-is-a-butterfly-valve\">What is a Butterfly Valve?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nButterfly Valve is a valve that can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of Ball Valves, which allows for quick shut-off. Butterfly valves are generally favored because they are lower in cost than other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:generateblocks\/button-container {\"uniqueId\":\"6d8495a3\",\"isDynamic\":true,\"blockVersion\":2} -->\r\n<!-- wp:generateblocks\/button {\"uniqueId\":\"3d442e11\",\"hasUrl\":true,\"target\":true,\"backgroundColor\":\"#0366d6\",\"textColor\":\"#ffffff\",\"backgroundColorHover\":\"#222222\",\"textColorHover\":\"#ffffff\",\"paddingTop\":\"15\",\"paddingRight\":\"20\",\"paddingBottom\":\"15\",\"paddingLeft\":\"20\"} -->\r\n<a class=\"gb-button gb-button-3d442e11 gb-button-text\" href=\"https:\/\/zecovalve.com\/contact\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET BUTTERFLY VALVE PRICE<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Types of Butterfly Valves<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li><strong>Concentric Butterfly Valve<\/strong>\r\n<ul>\r\n \t<li>The most basic design of a butterfly valve is a centric or concentric butterfly valve. The stem passes through the disc\u2019s centerline, and the seat is the inside diameter periphery of the valve body (Figure 4 on the left). This zero-offset valve design is known as resilient-seated because efficient sealing relies on the flexibility of the rubber seat. When closing, the disc first comes into contact with the seat at around 85\u00b0 during a 90\u00b0 rotation.

In some applications, bubble-tight shut-off cannot be achieved using double offset butterfly valves.
