The Duo ball valve is available in the same length as a standard valve and provides a compact and economical alternative to several valves.\r\n\r\n\r\n\r\n\r\n\r\nThe Duo Ball Valve (DBV) is designed for applications with extremely high safety requirements. The DBV consists of two ball valves, which are equipped on request with two independent barriers. Therefore, the safety factor could be increased 4 times compared to a standard ball valve. Due to the double isolation and bleed function each ball valve is tight on both the upstream and downstream sides.\r\n\r\n\r\n\r\n\r\nFeatures of INTEC Duoball Valve<\/h2>\r\n\r\n\r\n\r\n\r\n \t- \r\n

What is DBB Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nA double block and bleed valve are like having three valves in one.\r\n\r\n\r\n\r\n\r\n\r\nAPI 6D defines a double block and bleed valve as a \"single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a means of venting\/bleeding the cavity between the seating surfaces.\"\r\n\r\n\r\n\r\n\r\n\r\nThere are a couple of different styles of double block and bleed valves. One style has two independently seating valves inside, with a bleed or drains valve. This configuration is referred to as a double isolation and bleed (DIB). The DIB valve can isolate either side of the valve (bi-directionally) to vent or bleed the cavity and isolate piping.\r\n\r\n\r\n\r\n\r\n\r\nThis trunnion style ball valve from ZECO provides a double block and bleed in a single valve. This style can isolate piping on both sides of the valve (uni-directionally) to vent\/bleed the valve cavity between the seats.\r\n\r\n\r\n\r\n\r\n\r\nUsing a single double block and bleed valve system versus 3 separate valves saves installation time, weight on the piping system, and space. It also cuts down the number of leak paths to the atmosphere, reducing the risk of hazards when transferring liquids dangerous to humans or the environment.\r\n\r\n\r\n\r\n\r\nFeatures and Benefits of DBB Valve<\/h2>\r\n\r\n\r\n\r\n\r\nDouble Block and Bleed valves have been developed to substitute the process of bolting the individual valves together to provide dual insulation.\r\n\r\n\r\n\r\n\r\n\r\nThis new model provides excellent savings in weight, space, and installation time, particularly for insulation in the instrument or instrument cage. These weight savings will amount to up to 60% and tests have shown that a time savings of 70% on installation is also possible. The biggest benefits must be seen, however, in reducing the leakage pathways into the environment, thus reducing the possibility of possible dangers.\r\n\r\n\r\n\r\n\r\n\r\nDual isolation is an essential requirement when maintenance is performed downstream of the first isolation valve. Cavity venting is given by either a ball or a globe vent valve such that the compressed pressure between the two isolation valves is vented safely.\r\n\r\n\r\n\r\n\r\n\r\nThese valves have also grown to incorporate the role of chemical injection and sampling points. In-built control valves are also incorporated into these valves.\r\n\r\n","parent":0,"count":4,"filter":"raw"},{"term_id":3963,"name":"stem extension intec","slug":"stem-extension-intec","term_group":0,"term_taxonomy_id":3963,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3964,"name":"tandem-3-way ball valve","slug":"tandem-3-way-ball-valve","term_group":0,"term_taxonomy_id":3964,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3962,"name":"tank bottom ball valve intec k521","slug":"tank-bottom-ball-valve-intec-k521","term_group":0,"term_taxonomy_id":3962,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":3277,"label":"INTEC Duoball Valve"},{"value":3963,"label":"stem extension intec"},{"value":3964,"label":"tandem-3-way ball valve"},{"value":3962,"label":"tank bottom ball valve intec k521"}]},"yoast_head":"\nTank Bottom Ball Valve Intec K521 - Valve Supplier | 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\/filling-of-crystalline-media-zeco-valve-api-approved-valve-manufacturer.html\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Tank Bottom Ball Valve Intec K521 - Valve Supplier | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"Description of Tank Bottom Ball Valve Intec K521 Minimal Dead Leg: Flush mount tank valves are typically welded to the lowest part ...
