Where are Butterfly Valves Used

1. Where are Butterfly Valves Used?

2. Introduction • 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. Uses of Butterfly Valves • 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. Regulating Fluid Flow • 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. FLOW ISOLATION • 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. Backflow Prevention • 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. As Throttling Valves • 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.

8. Where can you find butterfly valves? • HVAC • Vacuum services • Aerospace sectors • Refrigeration and Air Conditioning systems • Irrigation and agricultural needs • Corrosive processing • Lubrication • District heating, mining and shipyards • Petroleum Industries • Wastewater treatment

9. Conclusion • 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.
