Butterfly valve is a
disc mounted on a rotating shaft. When completely shut down, the disk will completely block the
circuit. When fully opened, the disc is at right angles to the air or liquid flow. The advantage
of a butterfly valve is that it is relatively cheap to manufacture and maintain. They are the
most common valves in large-capacity water supply systems such as urban waterworks.
They can be used for dirty liquid applications such as sewage or river water control. When the
butterfly valve is fully opened, the butterfly disc is still in the flow line of the valve, so
there is always a pressure drop on the butterfly valve. In addition, if the differential
pressure on the butterfly valve is large, it may be difficult to open the valve. Some
applications require a bypass valve to reduce the pressure differential before large butterfly
valves can operate.
PVC plastic butterfly
valve according to the different medium has a variety of optional material, corrosive resistance
is strong , adapt to large diameter, small volume, light weight, health non-toxic material, easy
maintenance and replacement.
Fleyenda butterfly Valve offer a range of wafer, lugged & tapped butterfly valves in various
construction materials allowing them to be used in many applications including heating & air
conditioning, water distribution & treatment, agricultural, compressed air, oils and gasses.
We can also offer a range of manual, pneumatic, electric and hydraulic actuators to
suit.
