Subsea Check Valves 产品详情

As a supplier of equipment to the petroleum industry for more than twenty years, BuTech Pressure Systems offers an extensive line of check valves, needle valves, 2-, 3-, 4- and 5-way ball valves with 3/16" to 1" ports (4.7mm to 25.4mm), as well as fittings, tubing and related equipment for petroleum production.

Our sub-sea valves are custom designed for instrumentation, process control and chemical injection applications in the harshest environments. Designed for Remote Operated Vehicle (ROV) operation, these valves provide rugged protection, safety and reliability in template control panels, sub-sea wellheads and christmas trees.
Manufactured to meet the requirements of NACE MR-01-75, API spec. 6A and 17D, and numerous other specifications, BuTech sub-sea valves ensure trouble-free operation in hydrogen sulfides, corrosion inhibitors, paraffin thinners, hydraulic fluids and many other chemicals.

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 control the increasing temperature and pressure requirements at these greater depths.
 
BuTech’s subsea, relief, needle, ball, double block and bleed valves, and assemblies are installed in some of the oil and gas industry’s most challenging applications. From ball valves for onshore and topside applications to subsea valves performing in the harsh environments of the deepest offshore waters, BuTech leads the industry in performance, safety, and reliability.
