In subsea critical systems, nothing is more important than structural integrity to assure performance, safety and reliability. BuTech API 6A (19th ed.), ISO 10423:2003 PRs, Annex F/PSL3G qualified valves ensure the highest quality and most reliable performance for pressure control systems, throughout the entire life of the subsea structure. BuTech subsea valves meet performance, safety and reliability expectations in the deepest water and harshest environments in the offshore oil and gas industry. As wells have become deeper, BuTech has been a leader at developing new and innovative ways to...
