Steel and Stainless Steel Ball Valve (API 6D)
Steel and stainless steel ball valve manufactured for high-pressure and high-temperature duty in oil, natural gas, chemical and energy pipelines, in accordance with API 6D and ASME B16.34 standards. Full quarter-turn opening and closing; full-bore body design minimises pressure drop.
ASTM A216 WCB cast steel body and CF8 / CF8M stainless steel ball with PTFE-seated Flanged models available in Class 150 and Class 300 from 2″–12″; all CF8M stainless models supplied at the same sizes. For smaller bores, ASTM A105 forged steel and F316 stainless steel with R-PTFE / C-graphite-seated Class 800 Socket-Weld models (1/2″–2″) are available. For high-temperature and erosive fluid duty, metal-seated stainless steel models are available from 4″–16″.
