Specialityalve is leading high-quality Double Block and Bleed ball Valve Manufacturer in India. Double Block And Bleed ball Valve means there are two seating surface that are in closed position in a single valve which provide a seal against the pressure from both the ends of valve with a means of venting/bleeding the cavity between the seating surfaces.
Application of Double Block and Bleed Valves:-
Double Block and Bleed ball Valve are used in applications where critical isolation is needed to ensure that leakage does not occur.
Both the valves can be used in a various applications such as LNG, petrochemical, transmission and storage, natural gas industrial processes, mainline and manifold valves in liquid pipelines, and refined products transmission lines.
The other application in which Double Block and Bleed ball Valve are used is the meter calibration market. Every closed valve in the meter system must seal drop tight. Even a small leak will cause errors in the meter calibration, and the incorrect meter factor will persist until the next proving operation, costing significant sums. Choosing the correct API-verified Double Block and Bleed ball Valve can help ensure correct calibration almost every time.
A Double block and bleed Ball valve is usually in the form of quarter turn valve which generally uses a perforated, hollow & pivoting ball for controlling flow through it. It generally opens when the hole is in the line with the flow of liquid and it is closed when it is pivoted at 90 degrees angle by the valve’s handle. The handle’s alignment lies flat with the flow when it opens, and becomes perpendicular to it when it is closed. Ball valves are reliable and durable. Ball valves always perform excellent even after many cycles, they closes securely even after long gap of disuse. These kinds of properties make them as best choice for shutoff as well as controlling applications. . It can also be set at quarter-turn or half-turn positions for reducing or increasing pressure and fluid flow level. Automated ball valves are controlled with pneumatic or an electric actuator.
