what is the Difference between a Butterfly Valve and Gate Valve?

Butterfly valve and gate valve are one of the popular valves in the market. Let’s take a closer look at each of its features and what makes it so unique and effective.

Butterfly valve

Butterfly valve and gate valve are part of the same family. It has a resourceful variation and generally, the butterfly valve comes in numerous shapes and sizes. The gate within the butterfly valve remains fixed and swivels around an internal axis. The shape of the internal gate swiveling is the origin of the butterfly name.

Gate valve

The gate valve functions as a gatekeeper. A movable gate inside the valve allows flow or blocks it. This movable gate is controlled by a mechanical assist such as a screw or lever, which lifts or lowers the gate within. Gate valves do come in many shapes and sizes but tend to be large and are designed to be controlled by a single individual.

The butterfly valve & gate valve has almost the same function, which is to allow and block the flow. However, there are some advantages and disadvantages for both the valves, hence choosing the correct valve is very important. 

What are the differences and key points in choosing Butterfly Valve and Gate Valves?

Gate valves perform better under pressure compared to the butterfly valve. Its construction and usage can keep going without creating any undue pressure fluctuations.  

In terms of durability, gate valves perform better than the butterfly valve. Although butterfly valves are produced with a higher pressure tolerance, the design guarantees a higher rate of wear.

Regardless the valve is being opened or closed, its seal is constantly indirect exposure to flow velocity, contrasting the gate valve. Once activated, parts of the gate valve are visible to flow for very short bursts of time.

Butterfly valves are smaller and more compact in terms of size. Hence, it allows them to be more versatile in their use than gate valves.

In terms of price, butterfly valves are cheaper than gate valves.

Both valves are designed to function as a conduit of flow and not as a regulator. Neither is designed to be used continuously. Once they are released, the flow is unregulated.

At EC Pneumatic & Hardware, we take great pride in sidestepping many of the concerns faced by both of these valves. Our valves not only perform perfectly from the get-go but actually become better over time. These valves outdo all others in their tolerance of high pressure and corrosion, with the extra ability to regulate flow. You can be assured that our valves will not flop on the job.
