Butterfly valves are similar to ball valves in terms of operation. They are both quarter-turn valves used to stop, regulate, start and throttle flow, you can use a butterfly valve for handling large volumes of fluid.

2.  Butterfly valves are similar to ball valves in terms of operation. They are both
quarter-turn valves used to stop, regulate, start and throttle flow, you can use a
butterfly valve for handling large volumes of fluid.
 When the butterfly valve is fully closed, the disk completely blocks the line. When
the butterfly valve is fully opened, the disc is at a right angle to the flow of gas or
liquid.

3.  For on/off service or start/stop flow control – You can use any size of valve for this
application. Also, this operation requires a low-pressure drop during the opening
position.

 As regulating control valves – this application requires more attention on which
type of valve and size to use. You should also be able to identify the medium, type
of fluid, mode of operation and installation and the pressure drop. Some of these
information for calculation can be determined by the valve designer or engineer.

4.  Butterfly valves are widely used for regulating fluids. As a regulating valve, this is
done through the action of the actuator that communicates with the stem and disc
assembly of the valve.
 The degree of angular opening translates to an exact amount of fluid that goes
through the valve. Thus, the flow rate of the system is controlled through the
actuators

5.  Butterfly valves can be used for flow isolation because of their lightweight feature,
easy manipulation and quarter-turn action.
 However, when you use a butterfly valve as an isolation valve, you need to make
sure that it would not negatively affect your system performance.
 For example, in pumping systems, we desire a smooth flow of fluid towards the
pump impeller. This is to avoid system losses and cavitation. In order to do this,
vortex formation should be eliminated or reduced.

6.  Some food manufacturing processes require aggressive wash down procedures in
which butterfly valves can be used for backflow prevention during this process.
Backflow prevention is necessary as food processing plants should be clean and
operate in extremely sanitary conditions.

7.  Butterfly valves are commonly used for regulating large fluid flows, including
viscous slurries, but it should be noted that they are not a good choice for precision
throttling.
 However, recent developments have enabled butterfly valve manufacturers to
offer valves that can throttle quite accurately.
 For throttling services, you can find high-performance butterfly valves a way to
go. They are manufactured with a higher industry standard and are meant for
large high-pressure and high-temperature applications.

9.  Butterfly valves are used for applications that require handling large volume
capacities. It can be used for flow control and regulation and on/off service.
 Although butterfly valves can be used as isolation valves, the piping system
should be carefully designed to eliminate system losses. Choose the best butterfly
