Abstract

Ball type barrier valves for deepwater applications require sealing across the ball at temperatures excess of 400°F and a hold pressure of 15,000 psi. Elastomeric seals have limitations due to their natural glass transitional temperatures. The present seal is manufactured out of spring material and can operate in the high pressure and high temperature environment. This seal has two components; both of these components are made out of spring material. The seal seats on the small groove of the ball seal with certain preload. The C-Ring seats at the bottom of the groove and the Top Ring seats above the C-Ring. Seal surfaces can be coated with tungsten carbide to prevent damaged as number of cycles increases.
