Les vannes papillon ont d&#039;excellentes caract\u00e9ristiques d&#039;\u00e9tranglement. Ils peuvent r\u00e9pondre \u00e0 la fois aux pressions et au d\u00e9bit, de sorte que la r\u00e9ponse du d\u00e9bit soit lin\u00e9aire. Les vannes papillon sont \u00e9galement compactes et faciles \u00e0 utiliser et ont une grande plage de r\u00e9glage.

Throttling valves are regulator valves. Some people use the term \u201ccontrol valves\u201d to mean throttling valves. The truth is, there is a distinct line defining the two. Throttling valves have discs that do not only stop or start media flow. These discs can also regulate the amount, pressure, and temperature of media passing through in any position prescribed.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThrottling valves will have a higher pressure at one end and a lower pressure at the other end. This closes the valve, depending on the degree of pressure. One such example is a diaphragm valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOn the other hand, control valves will control the flow of media with the use of an actuator. It cannot function without one.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nPressure and temperature disrupt the flow of media so control valves regulate these. Also, these valves can change the flow or pressure conditions to match the required piping system conditions.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn this sense, control valves are specialized throttling valves. That being said, control valves can throttle but not all throttling valves are control valves.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe best example is the hydraulic system where an outside force has to release the vacuum so gas can enter the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Can Butterfly Valves be Used for Throttling?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nButterfly valves are another common type. They have a disc that pivots at right angles to the flow path and seals against seats in the valve body when fully opened. Butterfly valves have excellent throttling characteristics. They can respond to both pressures and flow so that the flow response is linear. Butterfly valves are also compact and easy to use and have high rangeability. In addition to throttling, they have good rangeability.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAmong the most common valves, the butterfly valve is the most suitable for throttling. A full quarter turn can open or close the valve. For throttling to happen, it only needs to open a bit for the media to pass.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nUnlike gate valves, butterfly valves can be used for throttling or regulating flow as well as in the fully open and fully closed position. The pressure loss through a butterfly valve is small in comparison with the gate valve. They are generally used for handling large flows of gases or liquids, including slurries, but should not be used for throttling for extended periods of time.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>How to Choose Throttling Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nEach type of throttling valve has its advantages and limitations. Understanding the purpose of implementing a throttling valve always narrows down the choices for the right kind of throttling valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Valve Size\r\n<\/strong>The right valve size means doing away with future valve issues. For example, a valve too large means limited throttling capacity. Most probably, it would be near its closed position. This makes the valve more prone to vibrations and erosion.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFurthermore, the valve that is too big would have additional fittings as an adjustment to the pipes. The fittings are costly.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Material of Construction\r\n<\/strong>The valve body material is an important aspect when choosing the throttling valve. It should be compatible with the type of material that would pass through. For example, chemical-based media should pass through a non-corrosive valve. Media that tends to reach high temperature or pressure should pass into a strong alloy with an internal coating.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Actuation<\/strong>\r\nActuation also plays a big role in choosing the right throttling valve. In pipeline applications, there are instances where strong pressure is present. A manual actuator may not be efficient in opening or closing the valve because of that.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Connections\r\n<\/strong>How the valve is connected to the pipes is also worth considering. It is important to adapt to the existing pipe connections rather than the pipes adapting to the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIt is more cost-effective to suit the valve to the existing pipe requirements. For instance, when the pipe ends have flanges, the valve should also have flanged end connections.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Industry Standards\r\n<\/strong>Industry standards are just as important. There are standards for the type of material to use for a particular media. There are also standards on end connections or the thickness of the metal to use for the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSuch standards bring safety to applications. There is often an increase in temperature and pressure when using throttling valves. That, it is vital to understand such standards for the safety of everyone.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":1,"filter":"raw"},{"term_id":3781,"name":"flowseal butterfly valve","slug":"flowseal-butterfly-valve","term_group":0,"term_taxonomy_id":3781,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2255,"name":"high performance butterfly valve","slug":"high-performance-butterfly-valve-2","term_group":0,"term_taxonomy_id":2255,"taxonomy":"post_tag","description":"","parent":0,"count":5,"filter":"raw"},{"term_id":3783,"name":"throttling butterfly valve","slug":"throttling-butterfly-valve","term_group":0,"term_taxonomy_id":3783,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":3782,"label":"Butterfly Valve Throttling"},{"value":3781,"label":"flowseal butterfly valve"},{"value":2255,"label":"high performance butterfly valve"},{"value":3783,"label":"throttling butterfly valve"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Butterfly Valve Throttling - Flowseal Butterfly Valve | ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/fr\/high-performance-butterfly-valves-for-on-off-and-throttling-service-zeco-valve-blog.html\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Butterfly Valve Throttling - Flowseal Butterfly Valve | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"Can Butterfly Valves Throttling?
