Double Block and bleed valve

 Double Block and bleed valve

   Double Block and bleed valve(DBB valve) is designed to replace the complex form of multiple valve connections in traditional pipelines. Double block and bleed valve can reduce leakage points in the system, quickly achieve emissions, and shut down functions. Double block and bleed ball valve minimizes installation space, saving weights , Simplified installation procedures, Reduce pressure in the piping system, Convenient instrument cleaning and maintenance, reducing costs.

    Double block and bleed valve has two series of full port and reduced port. The inside diameter of the full port DBB ball valve is the same as the inside diameter of the pipeline, which not only has the smallest fluid resistance, but also facilitates pipeline cleaning. The fluid resistance of the reduced-diameter ball valve is much lower than that of the same-diameter globe valve, and the weight is about 30% lighter than that of full port double block and bleed valve, which effectively reduces the production cost and price, so it has been widely used.
Third, the characteristics of DBB double ball valve (double block double discharge ball valve)
