Chaque processus est distinct en soi, n\u00e9cessitant des fonctionnalit\u00e9s particuli\u00e8res de contr\u00f4le de flux. Les \u00e9l\u00e9ments internes de la vanne comprennent la tige, le clapet, le disque, la surface d&#039;appui, etc. Il s&#039;agit \u00e9galement de la forme r\u00e9elle de l&#039;agencement du clapet et du si\u00e8ge. Les propri\u00e9t\u00e9s d&#039;\u00e9coulement de la vanne sont d\u00e9termin\u00e9es par la forme du clapet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pi\u00e8ces de garniture de soupape<\/h2>\n\n\n\n<p>La garniture sp\u00e9cifique \u00e0 la valve comprend le si\u00e8ge arri\u00e8re, les presse-\u00e9toupes, les entretoises, les guides, les bagues, les goupilles de r\u00e9tention et les ressorts internes.<\/p>\n\n\n\n<p><strong>Disque<\/strong><\/p>\n\n\n\n<p>Un disque est le composant initial de la garniture de soupape. Le disque est le composant qui, selon sa position, permet, \u00e9trangle ou arr\u00eate l&#039;\u00e9coulement du fluide. Le nom de la vanne provient souvent du type de disque. Les exemples incluent les vannes \u00e0 guillotine, \u00e0 bille, \u00e0 boisseau et \u00e0 pointeau, qui ont des disques de la m\u00eame forme que leur nom.<\/p>\n\n\n\n<p>Un disque de vanne peut \u00eatre forg\u00e9, moul\u00e9 ou fabriqu\u00e9. La face d&#039;\u00e9tanch\u00e9it\u00e9 du disque de vanne est parfois durcie pour am\u00e9liorer la r\u00e9sistance \u00e0 l&#039;usure. Le disque n\u00e9cessitait une surface de machine lisse pour r\u00e9duire la friction avec un si\u00e8ge\u00a0; le disque de soupape est un composant de maintien de pression.<\/p>\n\n\n\n<p>En position ferm\u00e9e, un disque repose contre le si\u00e8ge fixe de la vanne. La tige peut se d\u00e9placer via un actionnement manuel ou automatis\u00e9.<\/p>\n\n\n\n<p><strong>Si\u00e8ge<\/strong><\/p>\n\n\n\n<p>Le si\u00e8ge fournit au disque un endroit pour le fixer et le sceller. Une vanne peut avoir plusieurs si\u00e8ges. Il n&#039;y a qu&#039;un seul si\u00e8ge sur un robinet \u00e0 soupape et un clapet anti-retour \u00e0 battant. Un robinet-vanne et un robinet \u00e0 tournant sph\u00e9rique, quant \u00e0 eux, ont deux si\u00e8ges, l&#039;un en amont et l&#039;autre en aval.<\/p>\n\n\n\n<p>L&#039;efficacit\u00e9 du joint entre le disque de vanne et le si\u00e8ge est directement proportionnelle au taux de fuite du si\u00e8ge. Les si\u00e8ges de soupape peuvent \u00eatre des anneaux permanents ou amovibles. Les si\u00e8ges des vannes sont souvent viss\u00e9s, soud\u00e9s ou int\u00e9gralement moul\u00e9s ou forg\u00e9s, et sont renforc\u00e9s par traitement thermique ou par rechargement dur.<\/p>\n\n\n\n<p>Pour une \u00e9tanch\u00e9it\u00e9 optimale, la zone d&#039;assise doit avoir une surface polie fine. Pour les applications non critiques, des si\u00e8ges non m\u00e9talliques ont \u00e9t\u00e9 utilis\u00e9s dans certains robinets \u00e0 tournant sph\u00e9rique et robinets \u00e0 tournant sph\u00e9rique. Les fabricants de vannes produisent de nombreux styles de si\u00e8ges de vannes combin\u00e9s qui combinent des si\u00e8ges en \u00e9lastom\u00e8re et en m\u00e9tal pour atteindre l&#039;\u00e9tanch\u00e9it\u00e9 requise que les si\u00e8ges m\u00e9talliques seuls ne peuvent pas atteindre.<\/p>\n\n\n\n<p><strong>Si\u00e8ge arri\u00e8re<\/strong><\/p>\n\n\n\n<p>La banquette arri\u00e8re comprend un \u00e9paulement sur la tige et une surface de contact sur la face inf\u00e9rieure du capot. Lorsque la tige est enti\u00e8rement ouverte, elle forme un sceau. Il emp\u00eache les fuites de fluide dans la chambre de conditionnement et dans l&#039;environnement. Remarque : Pour des raisons de s\u00e9curit\u00e9, il n&#039;est JAMAIS recommand\u00e9 de changer la garniture lorsque la vanne est sous pression.<\/p>\n\n\n\n<p><strong>Tige<\/strong><\/p>\n\n\n\n<p>La tige relie le volant\/actionneur et le disque. Le disque de vanne se d\u00e9place et se positionne \u00e0 partir du mouvement de la tige. La tige de vanne transmet le mouvement requis au disque, au clapet ou \u00e0 la bille pour l&#039;ouverture, la fermeture ou le r\u00e9glage de la vanne. La tige relie l&#039;actionneur, le volant ou le levier de la vanne \u00e0 une extr\u00e9mit\u00e9 au disque \u00e0 l&#039;autre.<\/p>\n\n\n\n<p>Le mouvement lin\u00e9aire du disque ouvre ou ferme la vanne dans les vannes \u00e0 vanne et \u00e0 soupape, tandis que le disque tourne pour ouvrir ou fermer la vanne dans les vannes \u00e0 boisseau sph\u00e9rique, \u00e0 boisseau sph\u00e9rique et \u00e0 papillon. Les tiges sont g\u00e9n\u00e9ralement en acier inoxydable et se fixent g\u00e9n\u00e9ralement au disque via des connexions ou d&#039;autres moyens m\u00e9caniques.<\/p>\n\n\n\n<h2

These parts include valve seat(s), disc, glands, spacers, guides, bushings, and internal springs. The valve body, bonnet, packing, et cetera that also come in contact with the flow medium are not considered valve trim.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA Valve's trim performance is determined by the disk and seat interface and the relation of the disk position to the seat. Because of the trim, basic motions and flow control are possible. In rotational motion trim designs, the disk slides closely past the seat to produce a change in flow opening. In linear motion trim designs, the disk lifts perpendicularly away from the seat so that an annular orifice appears.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nValve trim parts may be constructed of assorted materials because of the different properties needed to withstand different forces and conditions. Bushings and packing glands do not experience the same forces and conditions as the valve disc and seat(s).\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFlow-medium properties, chemical composition, pressure, temperature, flow rate, velocity, and viscosity are some of the important considerations in selecting suitable trim materials. Trim materials may or may not be the same material as the valve body or bonnet.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>VALVE TRIM TABLE<\/h2>\r\n<!-- \/wp:heading

Trim levels will determine the most suitable application for your needs and the required materials for the internal components of the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe components affected by trim level changes include the:\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Body<\/li>\r\n \t<li>Bonnet<\/li>\r\n \t<li>Gate<\/li>\r\n \t<li>Seat<\/li>\r\n \t<li>Stem<\/li>\r\n \t<li>Bonnet seal ring gasket<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level AA<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAA is your general non-corrosive trim level. The material used in the AA trim level is 4130 for all components with the bonnet seal ring gasket being 1018.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level BB<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBB is used in a general and slightly corrosive environment. The body and bonnet will be made from 4130, the gate and seat will be 410 Stainless Steel, it will have a 17-4 Stainless Steel Stem, and a 316 Stainless Steel bonnet seal ring gasket.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level CC<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe CC valve trim type is used in a general, moderately corrosive environment with CO2. The body, bonnet, gate, and seats will all be 410 Stainless Steel. The stem will be made from 17-4 Stainless Steel, while the bonnet seal ring gasket will be 316 Stainless Steel.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level DD<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nDD-NL and DD-0.5 valve trim types are for sour, non-corrosive environments. All components in both trim levels are 4130 with the only difference being that DD-0.5 has a 17-4 Stainless Steel stem whereas the NL will most likely have a 4130 stem.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level EE<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nEE trim levels, like DD trim levels, are used in sour environments. EE-0.5 is used when the environment is slightly corrosive. EE-1.5 is used in highly corrosive environments with moderately abrasive CO2 present, and EE-NL is suitable when highly abrasive CO2 is present.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn all EE Trim levels, the body and bonnet are made from 4130 material. All gates, seats, and bonnet seal ring gaskets are Stainless Steel, with the gate and seats being 410 Stainless Steel and the bonnet seal ring gasket being 316 Stainless Steel. The difference in EE trim levels is the material used for the stems:\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>EE-0.5 uses a stem made from 17-4 Stainless Steel.<\/li>\r\n \t<li>EE-1.5 uses a stem made from 410 Stainless Steel.<\/li>\r\n \t<li>EE-NL uses either an Inconel 718 or a Nitronic 50 stem.<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level FF<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFF Trim levels are also used in a sour environment. FF-0.5 is for moderately corrosive environments with H2S. FF-1.5 and FF-NL are for highly corrosive environments with CO2 and H2S. The body, bonnet, gate, and seats are all made from 410 Stainless Steel, and the bonnet gasket is made of 316 Stainless Steel. The only part that is different between the three FF trim levels is the stem:\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>For FF-0.5 the stem is made from 17-4 Stainless Steel.<\/li>\r\n \t<li>FF-1.5 uses a 410 Stainless Steel stem.<\/li>\r\n \t<li>FF-NL uses either an Inconel 718 or a Nitronic 50 stem.<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim Level HH<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe last trim level is HH-NL, which is used in a highly corrosive and extreme service environment. The body and bonnet are both made from 4130 and have a 625 inlay throughout. The gate, seat, and stem are all made from 718 Inconel, and the bonnet seal ring gasket is 316 Stainless Steel.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":3,"filter":"raw"},{"term_id":3626,"name":"api trim chart","slug":"api-trim-chart","term_group":0,"term_taxonomy_id":3626,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":3622,"name":"api valve trim","slug":"api-valve-trim","term_group":0,"term_taxonomy_id":3622,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":3877,"name":"trim chart","slug":"trim-chart","term_group":0,"term_taxonomy_id":3877,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3623,"name":"Valve Trim Chart","slug":"valve-trim-chart","term_group":0,"term_taxonomy_id":3623,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_45013a-e2\"} \/-->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-what-is-valve-trim\">What is Valve Trim?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe trim, particularly the mating elements that regulate the stream to the controller\u2019s demands, is at the heart of the control valve.

The disc is the part that allows, throttles, or stops fluid flow depending on its position. Types of disks define the name of the valve such as gate, ball, plug, and needle valve\u2019s disk are also of the same shape as the name.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA valve disc could be cast, forged, or fabricated. The valve disk is sometimes required hard facing to improve wear resistance. The disk needed a smooth machine surface to reduce friction with the seat. The valve disk is a pressure-retaining part.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThat means the disk holds the pressure. When the valve is open, the disc does not perform pressure-retaining or -containing functions. However, when the valve is closed, the disc performs pressure-retaining functions.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA disc rests against the stationary valve seat when the valve is in the closed position. It can be moved away from the seat by the movement of the stem. However, in check and safety-relief valves, fluid flow and pressure move the disc away from the seat.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim - Seat<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe seat provides the seating surface for the disk. Here, you can see the gate valve seat in the above image. A valve may have multiple seats. In the case of a globe valve and swing check valve, there is one seat. A gate valve and ball valve have two seats; one on the upstream side and the other on the downstream side.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe valve leakage rate is directly proportional to the effectiveness of the seal between the valve disc and seat(s). Valve seats may be integral or replaceable rings. Valves are generally provided with a screwed, welded, or integrally cast or forged seat and hardened by heat treatment or by the hard facing of Stellite weld overlay.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA fine surface finish for the seating area is necessary for proper sealing. Some ball valves &amp; plug valves used the non-metallic seat for non-critical services. Valve manufacturers have developed several designs of combination valve seats involving elastomer and metal seats that are effective in achieving the desired leak tightness, which cannot be achieved only by metal seats.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim - Back Seat<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAnother component of the valve that does not maintain pressure is the back seat. A stem shoulder serves as the foundation of the back seat. The stem creates a seal when it is fully extended. As a result, the valve shell\u2019s leaking into the packaging chamber, and the environment is stopped.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim - Stem<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe stem connects the actuator and disk. It moves and positions the valve disk. The valve stem transports the required motion to the disc, plug, or ball for opening, closing, or positioning the valve. The stem connects the actuator, handwheel, or lever of the valve at one end and the disc on the other end.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn gate and globe valves, the linear motion of the disc opens or closes the valve, while in the plug, ball, and butterfly valves, the disc rotates to open or shut the valve. Stems are typically forged from stainless steel and connected to the disk by threaded or welded joints.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim - Yoke<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nYoke is another name for yoke arms. A yoke connects the valve\u2019s actual mechanism to the valve body or bonnet. The yoke and the bonnet are built as a single piece to cover multiple valves. The yoke nut and yoke bushing are located on the top side of the yoke.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe Yoke is constructed tough enough to endure the forces, moments, and torque generated by the actuators.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Valve Trim - Yoke Brushings<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIt is the area where the valve stem enters through the top of the yoke and the internally threaded nut is held in place. Depending on which way the nut is rotated, the stem moves up and down in certain valves, such as gate and diaphragm valves. The yoke nut is positioned permanently over some valves, and the stem is rotated via it.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe yoke bushings are composed of softer material than the stem in order to need the least amount of effort to operate. On the valves that need a lot of effort to open or close, anti-freeze yoke sleeve bearings are provided. By doing this, the friction between the yoke bushing and the toughened stem will be reduced.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Valve Trim Chart<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe removable and replaceable valve internal parts that come in contact with the flow medium are collectively termed as Valve trim. These parts include valve seat(s), disc, glands, spacers, guides, bushings, and internal springs. The valve body, bonnet, packing, et cetera that also come in contact with the flow medium are not considered valve trim.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA Valve's trim performance is determined by the disk and seat interface and the relation of the disk position to the seat. Because of the trim, basic motions, and flow control are possible. In rotational motion trim designs, the disk slides closely past the seat to produce a change in flow opening. In linear motion trim designs, the disk lifts perpendicularly away from the seat so that an annular orifice appears.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nValve trim parts may be constructed of assorted materials because of the different properties needed to withstand different forces and conditions. Bushings and packing glands do not experience the same forces and conditions as the valve disc and seat(s).\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFlow-medium properties, chemical composition, pressure, temperature, flow rate, velocity, and viscosity are some of the important considerations in selecting suitable trim materials. Trim materials may or may not be the same material as the valve body or bonnet.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":3,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":2477,"label":"API 600"},{"value":3625,"label":"api 600 trim chart"},{"value":3621,"label":"API Trim 12"},{"value":3626,"label":"api trim chart"},{"value":3622,"label":"api valve trim"},{"value":3877,"label":"trim chart"},{"value":3623,"label":"Valve Trim Chart"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>API 600 Valve Trim Chart | 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\/api-600-valve-trim-number-chart-service-suitability-zeco-valve-company-professional-valve-manufacturer.html\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"API 600 Valve Trim Chart | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"What is API 600 Standard?
