- Subsea Ball Valves



Subsea ball valves are externally sealed design for depths to 14,000 feet (4200 meters).  All valves are internally pressure tested to at least 50% over rated pressure and have a typical service life guarantee of 25 years and Manufactured to meet the requirements of NACE MR0175, API Spec 6A & 17D, ASME, ANSI and various others. API 6A , 19th ed., ISO 10423:2003 PR2, Annex F/PSL3G qualified valves available.

Subsea ball valves are custom designed for instrumentation, process control and chemical injection applications. Remote operated vehicle (ROV) capabilities in template control panels, subsea wellheads and christmas trees.  Subsea ball valves provide trouble free operation in a variety of media including hydrogen sulfides, corrosion inhibitors, paraffin thinners, hydraulic fluids and other harsh chemicals, and s may be produced in any machinable metal with special seal materials. Standard materials include 316 cold-worked stainless steel and high pressure super duplex.

2-way ball valves come in 3/8’, 1/2” and 1” configurations; 3-way ball valves come in 3/16’, 3/8” & 1/2” configurations, and 4-way ball valves come in a 3/8” configuration.
