High pressure DBB ball valve,RF NPT end

High pressure DBB ball valve,RF NPT end introduction
High pressure DBB ball valve,RF NPT end is floatng or trunnion monted structure,which has three valves in one.High pressure DBB ball valve,RF NPT end 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."
There are a couple different styles of double block and bleed valves. One style has two independently seating valves inside, with a bleed or drain valve. This configuration is referred to as a double isolation and bleed (DIB). The DIB valve can isolate either side of the valve (bi-directionally) to vent or bleed the cavity and isolate piping.
 
Using a High pressure DBB ball valve,RF NPT end system versus 3 separate valves saves installation time, weight on the piping system, and space. One Piece DBB Ball Valve with RF NPT end also cuts down the number of leak paths to the atmosphere, reducing the risk of hazards when transferring liquids dangerous to humans or the environment.

High pressure DBB ball valve,RF NPT end application
High pressure DBB ball valve,RF NPT end is most commonly used in the oil and gas industry, but can also be helpful in many other industries.
It's typically used where bleeding the valve cavity is required, where piping needs isolation for maintenance, or for any of these other scenarios:
Level Measurement
Pressure Measurement
Chemical Injection
Sampling
Flow Measurement
Prevent product contamination
Remove equipment from service for cleaning or repair
