DOUBLE BLOCK AND BLEED BALL VALVE (DBB BALL VALVE)

Product Description

Trunnion mounted DBB ball valve (Double block & bleed ball valve) is trunnion mounted structure,which has three valves in valve.High Pressure double block and bleed ball valve as a single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a means of vending/bleeding the cavity between the seating surfaces.The DBB double ball valve is designed to replace the complicated connection of multiple valves in the traditional pipeline. Reduce the leakage point in the system, quickly achieve emissions and shut down function. The DBB double ball valve saves the installation space limit. The installation program is simplified. Reduce the pressure of the pipe system.
