butterfly valve uses
Butterfly Valves work almost identical to Electric ball valves with
a flat disc connected to the actuator by a rod. Located outside of the valve
itself, the actuator controls the position of the disc which then controls the
flow of liquid. Controlling the amount of liquid flowing the pipes is the easy
with a few turns of the valve.
The metal disc found on the rod which
allows the flow of liquid or waste unchecked when turned a quarter turn, is
referred to as the "butterfly". Adjusting the valve controls whether the liquid
is interrupted or allowed to flow unchecked. Considered one of the main features
when using a butterfly valve, it is largely beneficial for industrial or
agricultural uses. The size of the butterfly valve is another as this type of
valve is much lighter and compact requiring less support when being used, unlike
the electric ball valve.
One of the most important and significant parts
of the butterfly valve is the resilient seat. This seat allows a seal to be
formed around the upper and lower points at the stem and disk edges when
compression or pressure is applied. Other parts of the butterfly disk are the
butterfly disk itself, the actuator, body, a notched plate used for positioning
the valve and the packing. If the seal is damaged, packing acts as backup
security giving an additional seal around the stem of the Butterfly Valve for
additional security and protection.
There is a wide range and variety of butterfly Valves available on the industrial market today with the best type by far
being those configured for pneumatic control. These disks actively make use of
an interactive gearbox and receive a signal from the valve operator for both
opening and closing the electric ball valve. Flexibility and ease of use are the
main advantages to this type of butterfly valve as it allows the option of
single or double actuation by the valve operator. With single actuation, a fail
safe is vital because in the event of a power loss the valve will still be able
to be closed securely. Double action valves, which do not loaded with a spring,
require signals each time they are opened or closed by the valve operator.
