Es un termopl\u00e1stico de ingenier\u00eda de alto rendimiento. Ofrece una excelente resistencia qu\u00edmica y al agua y no se ve afectado por la exposici\u00f3n continua al agua caliente o al vapor. Su estabilidad de temperatura es buena hasta 550 \u00b0F y es una alternativa de alta resistencia a los fluoropol\u00edmeros utilizados para asientos de v\u00e1lvulas. Estas propiedades lo convierten en una excelente opci\u00f3n de asiento para presiones elevadas combinadas con temperaturas elevadas. ZECO Valve ofrece asientos de v\u00e1lvula PEEK en dos grados, lleno y sin relleno. El relleno es una mezcla \u00fanica de rellenos de carbono\/grafito para garantizar propiedades del material consistentes y uniformes.

Needless to say, this can cause some serious issues such as leaks and catastrophic failure. The solution is to find a ball valve seat material that is highly resistant to permeation and an excellent choice would be PCTFE. In this week\u2019s blog post, we will talk about PCTFE Ball Valve Seats and how they are used in Low Permeation Applications.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOne of the best materials for a ball valve seat application where permeability is a problem would be PCTFE (Polychlorotrifluoroethylene), a thermoplastic chlorofluoropolymer. PCTFE is sometimes referred to as Modified PTFE or PCTFE, as well as by trade names Kel-F, Voltalef, and Neoflon. PCTFE is often thought of as a second-generation PTFE material that maintains the chemical and thermal resistance of PTFE along with its low friction. It is also similar to other fluoropolymers such as PFA or FEP.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOne of the defining characteristics of PCTFE is that it has a much more dense molecular structure and a low void and micro-porosity content when compared to similar ball valve seat materials. This gives it a very low permeability coefficient, which means that the likelihood of it swelling or popcorning is far lower than other materials. For example, its permeability for O2, N2, CO2, and H2 are 1.5 x 10-10, 0.18 x 10-10, 2.9 x 10-10, and 56.4 x 10-10 darcy, respectively.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nPCTFE also provides improved toughness and strength along with good deformation recovery and excellent creep and cold-flow resistance. In addition, it has a wide operating temperature range of -100\u00b0F to 500\u00b0F. In fact, it performs extremely well at cryogenic temperatures. Because of its low friction, it also results in a very low ball valve operating torque. PCTFE also exhibits zero moisture absorption and is non-wetting.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nPCTFE works well in operating environments where other polymers may fail. For example, it is well adapted to nuclear service that may involve high radiation exposure, is non-flammable (D 635), and is resistant to attack by the vast majority of chemicals and oxidizing agents. The only chemicals that might lead to slight swelling are ethers, esters, aromatic solvents, and halocarbon compounds.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":4,"filter":"raw"},{"term_id":1998,"name":"PCTFE Valve Seat Manufacturer","slug":"pctfe-valve-seat-manufacturer","term_group":0,"term_taxonomy_id":1998,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_7bd7e9-a7\"} \/-->\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=\"mailto:commercial@zecovalve.com\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET PCTFE VALVE SEAT PRICE<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-what-is-pctfe\">What is PCTFE?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nPCTFE(Polychlorotrifluoroethylene) is a fluorocarbon-based polymer.

It is suitable for utilizing in the temperature range of -200\u2103\uff5e150\u2103, especially for cryogenic applications such as oxygen, hydrogen, nitrogen, and more.

The nonmetallic seat ring is made from e.g. Teflon. The ring is held against the ball by an insert. For fire-safe service, a secondary metal-to-metal seating arrangement is required to omit leakage in the event that the soft seat material is lost during a fire. Soft seated valves are recommended for clean service only and are unsuitable for dirty\/abrasive service or high temperatures.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Double Beveled Sealing Ring<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe structure design of a double-beveled sealing ring has been adopted to reduce the friction between the ball and the sealing ring to achieve lower operating torque. When the medium pressure is low, the ball has a smaller contacting surface with a sealing ring, which introduces higher sealing pressure to ensure the sealing reliability. When the medium pressure gets higher, the contacting area between the ball and the sealing ring increases accordingly. A larger contact area reduces the sealing pressure to avoid the deformation of the sealing ring.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Cantilevered lips seat rings<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSeat rings with cantilevered lips are designed so that the ball contacts initially only the tip of the lip. As the upstream and downstream seats are pre-stressed on an assembly against the ball, the lips de\ufb02ect and put the seat rings into a torsion. When the valve is being closed against the line pressure, the lip of the downstream seat de\ufb02ects still further until \ufb01nally the entire seat surface matches the ball. By this design, the seats have some spring action that promotes good sealing action also at low \ufb02uid pressures. Furthermore, the resilient construction keeps the seats from being crushed at high \ufb02uid loads\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Pressure equalizing slots<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe seat ring shown is provided with peripheral slots, which are known as pressure-equalizing slots. During the closing of the valve, the maximum surge pressure occurs, during which the downstream seat can be forced to intrude into the ball port and the valve can become inoperative. The pressure equalizing slots prevents this potential failure. When pressure causes the upstream seat to move against the ball and the ball moves downstream, the pressure simply leaks into the valve body cavity through the relief slots. The upstream seat ring becomes pressure balanced. Downstream sealing prevents seat damage and lowers operating torque while providing full bidirectional capability. The seats with pressure equalizing slots also permit the valve to operate at a higher pressure differential with lower torques than double sealing valves in which there is sealing between both seats and the ball.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Soft Seat (Metallic Seat Ring)<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe metallic seat ring, containing a nonmetallic insert, usually requires spring force to achieve a tight seal. Due to springs, this design is not used in corrosive service. Even though this seat has a metal seat ring, it is categorized as a soft seated ball valve due to its use of soft material insert, which is in contact with the ball.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Metal to Metal Seats<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFor services unsuitable for soft seating, metal and ceramic seating are being used. In general practice, hard metal seated ball valves (typically stellite) are only used in severe service conditions such as high temperature, high erosion, corrosion or abrasion, slurry, etc. Metal seats are generally not bubble tight. Metal seats and balls are typically lapped in matching sets resulting in perfect roundness and fitness to ensure smooth operation and tight shut-off and achieving \u2018Zero Leakage\u2019. Metal seats come in different classes of Shut Off including Class IV, V, and VI. Metal Seat and Ball are fabricated from base metals coated with hard chrome, tungsten carbide, and Stellite.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":5,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":1997,"label":"PCTFE Valve Seat"},{"value":1998,"label":"PCTFE Valve Seat Manufacturer"},{"value":3258,"label":"peek seat"},{"value":3257,"label":"peek seat material"},{"value":3256,"label":"peek valve plates"},{"value":3235,"label":"Valve Seat Rings"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>PEEK Seat Ball Valve - PEEK Valves Seat | PEEK Valve Plates - ZECO<\/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\/es\/what-is-the-advantage-of-peek-seat-ball-valve-news-china-ball-valve-manufacturerfactory-and-supplier-ball-valve-api-6d-ball-valve-manufacturer.html\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"PEEK Seat Ball Valve - PEEK Valves Seat | PEEK Valve Plates - ZECO\" \/>\n<meta property=\"og:description\" content=\"Ball Valves Ball valves are used to control the flow of water, oil, steam, air, slurries, and corrosive fluids.
