Within its stated scope, ASME B16.34 treats wafer or flangeless valves installed between or against flanges as flanged-end valves. That standards convention does not prove that a specific Raymon product falls within the standard or is available in a particular configuration.<\/p>\n\n<p>For procurement, record wafer\/flangeless as a special flange-mounted arrangement and verify the exact body, flange compatibility, bolting, centering, sealing arrangement, face-to-face, support and any directional or dead-end limitation on the approved model drawing.<\/p>\n\n<figure class=\"raymonvalve-media\" data-image-status=\"live-verified\" data-attachment-id=\"14333\" data-evidence-role=\"non-evidentiary-engineering-illustration\" data-evidence-level=\"F0_UNVERIFIED\">\n  <img loading=\"lazy\" src=\"https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/08\/ball-valve-end-connection-anatomy.webp\" alt=\"Simplified installed-joint anatomy for flanged threaded socket-weld and butt-weld Ball Valve ends\" width=\"1200\" height=\"900\" loading=\"lazy\" decoding=\"async\" title=\"\">\n  <figcaption>Generic interface anatomy only; not a product section, weld detail or installation procedure.<\/figcaption>\n<\/figure>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-77228a59 elementor-widget elementor-widget-html\" data-id=\"77228a59\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t\t<h2 id=\"flanged-ball-valve-ends\">Flanged Ball Valve Ends<\/h2>\n\n<p>A flanged Ball Valve connects to mating pipe flanges through a joint system that includes the valve flange, pipe flange, facing, gasket, bolting and assembly controls.

Specialized flange-mounted or application-specific arrangements should be recorded separately and verified against the exact valve and piping system.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Is a wafer Ball Valve an end connection type?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>It is more precise for procurement to treat wafer\/flangeless as a special flange-mounted arrangement rather than a pipe-end preparation parallel to a thread or weld bevel. Confirm the exact model, mating flanges, bolting, sealing, centering and installation limits.<\/p><\/div>\n<\/details>\n<details>\n  <summary>What is the difference between socket-weld and butt-weld Ball Valve ends?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>A socket-weld joint inserts the mating pipe into a controlled socket before welding. A butt-weld joint joins prepared valve and pipe ends. The two routes require different geometry, fit-up and inspection information and must not be combined as a generic <code>welded<\/code> RFQ field.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Are flanged Ball Valves easier to remove than welded Ball Valves?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>Flanged construction may allow removal without cutting, but only after safe isolation and when the piping is supported and the layout provides bolt and flange-separation clearance. Welded ends normally require a controlled cutting and re-welding plan.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Can NPT, BSPT and BSPP threads be connected interchangeably?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>Do not assume so. Confirm the exact thread standard, form, taper or parallel condition, dimensions, sealing mechanism and approved adapter route, if any, before procurement or assembly.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Which Ball Valve end connection is best for high-pressure service?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>There is no universal answer from pressure class alone. Review the complete valve rating basis, pipe system, materials, design pressure and temperature, joint requirements, loads, installation, inspection and project specification.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Does a welded Ball Valve eliminate external leakage risk?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>No. A welded pipe-end joint removes a detachable gasketed or threaded joint at that location, but weld quality and other pressure-boundary interfaces still require design, installation, inspection and maintenance controls.<\/p><\/div>\n<\/details>\n<details>\n  <summary>What must an RFQ state besides flanged, threaded or welded?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>State the exact standard and edition, dimensions, rating basis, facing\/thread\/end preparation, joint components, pipe data, valve length, bore transition, installation and inspection requirements, replacement strategy and supplier deviations.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Does the flange standard also define the valve face-to-face dimension?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>Not automatically. Flange-system requirements and valve face-to-face\/end-to-end requirements have different roles. Verify both against the applicable project references and the approved valve drawing.<\/p><\/div>\n<\/details>\n<details>\n  <summary>Can a fully welded Ball Valve have flanged ends?<\/summary>\n  <div class=\"raymonvalve-faq-answer\"><p>Potentially, because body construction and pipe-end connection are separate classification axes. Product availability and the exact offered configuration must be confirmed from the controlled model datasheet and drawing.<\/p><\/div>\n<\/details>\n<\/section>\n  \n<section class=\"raymonvalve-engineering-note\" data-master-slot=\"evidence-boundary\" aria-labelledby=\"engineering-note\">\n<h2 id=\"engineering-note\">Engineering Note<\/h2>\n<p><strong>Purpose:<\/strong> help engineers and procurement teams distinguish connection labels from complete piping interfaces, identify missing inputs, normalize supplier offers and prepare an auditable RFQ.<\/p>\n<p><strong>Assumptions and limits:<\/strong> no exact Raymon Valve model, size range, rating, end availability, material, bore, face-to-face, torque, leakage result, welding route, qualification, test or certificate is approved by this article.
