Double Block And Bleed Ball Valve

 

Double Block and Bleed Valve is a side-entry ball valve, with either a bolted or welded body, designed for use in upstream, midstream and downstream oil and gas applications. 


It requires two in-line isolation valves and a bleed valve used to drain or vent trapped fluid between the two closure elements in order to safely isolate the downstream pipe. 

This feature can be achieved with one single valves complete with a bleed port between the obturators.
