DBB Floating Ball Valves with two seat sealing pairs provide pressure sealing at both ends of their valves in the closed position by means of venting/exhausting of the body cavity between the two seat surfaces. DBB seats are designed to provide highly reliable double sealing and venting. When the valve is closed, two independent seat sealing pairs work in tandem to effectively block the flow of media at both ends of the valve. This design not only provides excellent sealing performance under normal operating conditions, but also allows for leakage detection by means of a vent/exhaust method in the valve body cavity.
