Floating ball valves are mainly used for low-pressure service, as an alternative to trunnion mounted ball valves.With a double chip structure, the ball can float from one side to the other for reducing the operating torque and decrease the valve wear.

Trunnion mounted ball valves are designed for withstanding higher pressure matched to high or low temperature, widely used for a variety of applications for crude oil, natural gas pipelines and others.

DBB valves are engineered with one body and two balls, in order to secure more safety but also save weight and space in working environments where these factors are important, e.g. offshore platform.
