Where can a butterfly valve be used?

A butterfly valve is designed to regulate or isolate fluid flow in various piping systems, making it highly versatile. Its unique design incorporates a disc that rotates within the pipe to control the flow of liquid or gas. One of the most significant advantages of butterfly valves is their ability to maintain an effective seal while allowing for efficient flow in both directions.

Using a butterfly valve on the inlet and outlet of a water pump helps ensure proper flow control and pressure regulation, which is critical for maintaining optimal operation of the pump. The valve can be positioned either before the pump (inlet) to control the flow entering the pump or after (outlet) to regulate the flow of water being discharged. This flexibility in use makes them ideal for a variety of applications, extending beyond just water pumps.

In contrast, other options focus on more restrictive usages or specific applications, which do not capture the broader functionality of butterfly valves. For example, limiting their use to only the outlet of a water pump or associating them solely with high-pressure applications or refrigeration systems overlooks their versatility in general plumbing and fluid delivery systems.
