Double DBB fixed ball valve

One of the main advantages of the double block and bleed fixed ball valve is its ability to provide double isolation. The valve has double seat surfaces, which can effectively block the flow of media at both ends, thereby achieving safe and reliable isolation, maintenance and inspection of upstream and downstream pipelines. The dual isolation feature minimizes the risk of leaks, cross-contamination and compromised system integrity during maintenance or outages, providing enhanced safety and protection for personnel and equipment in critical process applications.

Another advantage of the DBB fixed ball valve is its integrated vent or chamber pressure relief feature that relieves trapped pressure or fluid between the two seat surfaces.

Additionally, fixed ball valve designs include features that promote efficient flow control and minimal pressure drop. The smooth, precise operation of ball valves effectively regulates flow, reduces turbulence and energy loss, and provides reliable performance in a variety of fluid and gas applications. This efficient flow control capability helps improve the overall operating efficiency and cost-effectiveness of fluid and gas systems using this valve.
