RING-O®
Ball and Gate Valves
Cameron’s RING-O® brand started as a private, family owned company in 1979, focused on the design
and production of gate, globe and check valves for severe service applications. The company benefited
from a relationship with sister company and forging shop, RING-MILL. The combination helped pair
sophisticated materials with proven valve designs, with much of the companies’ knowledge dating back
to the early 1900s when they were producing agricultural equipment with a water-driven hammer (also
known as a hydraulic trip hammer).
The modern demand for deepwater oil exploration gave rise to the expanded range of RING-O ball and
gate valves for subsea service. Since 1985, the RING-O team has utilized the most current technology to
provide reliable solutions to the challenging environments of subsea pipelines and manifold
applications. Only technologically advanced equipment can maintain integrity in ultra-deep waters, and
that’s exactly where RING-O ball and gate valves were born and have continued to develop since their
inception.
In 1999, as a voluntary contribution to the joint effort for the development of deepwater technology,
RING-O was part of the Deep Star Study project team. This team was created to research and develop
equipment for operation in more than 10,000 ft (3048 m) water depth. The study brought together the
industry’s leading experts in a common multidiscipline forum to address technical issues facing
economically viable deepwater production. The study offered the RING-O team a valuable platform to
learn and apply the best technology to both gate and ball valve designs. When the registered RING-O
brand joined the Cameron family in 2005 as part of the Dresser Flow Control segment acquisition, it
boosted Cameron’s subsea strength significantly.
Reliability and service life are key requirements in subsea environments, and Cameron’s RING-O testing
capability is well-known in the industry. Manufactured at the Colico, Italy, facility, the RING-O product
line’s team is equipped with one of the largest and most advanced hyperbaric chambers in the world –
capable of simulating water depths to 13,123 ft (4000 m).
With the assurance provided by uncommonly advanced in-house testing facilities, coupled with leading
technological expertise, it is not hard to see why Cameron’s RING-O line of ball and gate valves are
sought after by today’s most recognized global oil and gas pipeline operators.
