Subsea Valves, Chokes, and Chemical Injection Metering Valves

Industry-leading valve technology that meets the demanding requirements of subsea applications – for shallow or deepwater, subsea trees or manifolds.

The Cameron Subsea Valve Center of Excellence was founded in 1979 as the RING-O subsea valves manufacturing facility, with a focus on the design and production of gate, globe, and check valves for severe service applications.

Subsea production and pipeline transmission are considered critical service applications for valves because of the high pressures, extreme temperatures, and remote location of the equipment. Today, we offer a range of ball valve sizes and pressure ratings qualified to meet the demanding requirements of subsea applications.
