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.
Benefits:
· Compact in
design
· Reliable &
Durable operation
· Seals close
securely even after long time gap of disuse.
· Ball valves are
basically useful in fluid shut down & controlling applications that need to
avoid losing pressure, such as oil and gas production facilities.
