DBB Ball Valves

What is a DBB ball valve?

Double block and bleed ball valve is a ball valve with two valve seat surfaces. When the valve is closed, the pressure in the valve body cavity between the two valve seat surfaces can be released to seal the pressure from both ends of the ball valve at the same time.
Note: when only one side is under pressure, this kind of ball valve does not have effective double isolation performance.
The DBB ball valve is two double safety devices, which is composed of two main block valves and a relief valve. They are designed in a valve body structure. This special structure minimizes the possibility of leakage during pipeline connection, integrates the valve, pipeline and connector into a compact structure, and reduces the overall size and weight of the valve.
