Full bore floating DBB ball valve

Full bore floating DBB ball valve introduction
Full bore floating DBB ball valve (Double block & bleed ball valve) is mainly suitable for the instrumentation but is also required as an alternative to the in-line installation of two valves.Thanks to Full bore floating DBB ball valve, it is possible to have the same result reducing costs,  overall dimensions and the ability to bleed off the plant, by controlling a potential leakage of the plant.Full bore floating DBB ball valve is recommended for any pressure class and ensure long-lasting seal.They can be supplied both in the Trunnion and in the Floating version.

The Full bore floating DBB ball valve is the abbreviation for the double block and bleed ball valve.some of DBB ball valve has two balls and one or two needle valves,the two ball valves can opend and closed the medium and two needle valves can discharge pressure of the valves,the ball valve is designed to replace the complex form of the connection of multiple valves in traditional pipes,so as to reduce leakage points in the system and realize fast discharging and closing. The DBB ball valve saves the installation procedures,reduces pressure in the pipe system,facilities instrument cleaning and maintenance and lowers the cost.
