Ball Valves Leak Sealing
A unique solution to a common problem
The primary seals in a high pressure ball valve are mounted in a “seal ring”
This seal ring is equipped with peripheral seals which cause the line pressure to energize the primary seals against the ball
Valve manufacturers provide grease injection ports. When grease is injected:
- The additional pressure helps to seat the primary seal
- The grease can fill minor surface imperfections in the ball and seal
Furmanite has a solution for this.
