DOUBLE BLOCK AND BLEED BALL VALVE

Product Description

Double block bleed floating DBB Ball Valve can be double flange or single flange design, Double block bleed floating DBB Ball Valve have 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,Double block bleed floating DBB 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.Double block bleeding floating DBB Ball Valve saves the installation procedures,reduces pressure in the pipe system,facilities instrument cleaning and maintenance and lowers the cost.
