Double Flanged Butterfly Valve Manufacturer in
India
Speciality Valve is a trusted Double Flanged
Butterfly Valve Manufacturer in India. We supply
to dometiscally to states like West Bengal ,
Karnataka and Tamil Nadu. A double flanged
butterfly valve is a mechanical device used in
fluid control systems, which has two flanged
connection points for easy installation and
secure sealing within pipelines. This valve
consists of a circular disc or "butterfly" that
turns within the pipeline to regulate the flow of
fluids. Its main purpose is to efficiently
control the flow of liquids or gases by changing
the position of the disc, either fully open or
fully closed, or at various positions, which
allows precise control of the fluid flow rate and
direction. The double flanged design ensures a
robust and leak-proof connection to the pipeline,
making it suitable for a wide range of industrial
applications where reliable fluid control is
essential.

Working Mechanism A double-flanged butterfly
valve operates similarly to a standard butterfly
valve but features additional flanges at both
ends, enhancing its sealing capabilities and
structural integrity. Like its single-flanged
counterpart, it employs a disc that rotates
within the valve body to control flow. When fully
open, the disc aligns parallel to the flow
direction, minimizing resistance and allowing for
unrestricted passage. Conversely, when closed,
the disc turns perpendicular to the flow,
effectively blocking it. The double-flanged
design offers advantages in terms of installation
flexibility and maintenance, as it can be easily
mounted between flanged connections without the
need for additional support. This valve variant
is particularly suitable for high-pressure
applications where robust sealing is paramount.
Its relationship with the standard butterfly
valve lies in its fundamental operation
principle, with both variants leveraging the
rotational motion of a disc to regulate fluid
flow. However, the double-flanged configuration
extends this concept by incorporating additional
flanges, thereby enhancing its sealing
capabilities and adaptability in diverse
industrial settings.
The main parts of a double-flanged butterfly
valve Body The main outer casing of the
valve that houses the internal components.
Disc The circular or semi-circular plate that
rotates inside the body to control flow.
Stem A rod that connects the actuator to the
disc, allowing it to be turned for opening or
closing. Actuator The mechanism responsible
for operating the valve, which can be manual,
pneumatic, hydraulic, or electric. Seat The
surface against which the disc seals to control
flow and prevent leakage when the valve is
closed. Flanges The raised rims at both
ends of the valve body, which are used for
connecting the valve to pipelines or other
equipment. Bolts and Nuts Fasteners used to
secure the valve to the pipeline or other
equipment.
