Difference Between Butterfly Valves and Gate Valves

Gate valves

As the name implies, the main function of a valve is as a gatekeeper. The gate is the main part of gate valves. A movable gate within 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 come in many shapes and sizes but tend to be large. Think of the valves controlling flow of water in main water supply pipes. In spite of their sometimes prodigious size, gate valves are designed to be controlled by a single individual.

Butterfly valves

A close cousin of the gate valve, and an ingenious variation, a butterfly valve can also come in many shapes and sizes. Such a valve also functions by using an internal gate. The difference between this and a gate valve is in the way the gate operates within the valve.

Unlike the gate valve, 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.

The butterfly valve has the same function as the gate valve, which is allowing and blocking flow. There are, however, some advantages and disadvantages to both types of valves, and it’s important to keep that in mind when choosing either valve.

FEID AVALVE is the top ranking China double offset butterfly valve manufacture. The annual output of high performance butterfly valve is more than 100,000,000 set.

The API 607 fire safe high performance butterfly valve is also in FEIDA VALVE product range. Our fire safe butterfly valve is certificated by American Petroleum Institute (API) according to API 607 standards.

FEIDA also build up a dustless workshop to produce ultra-clean valve for some critical working condition such as nuclear industry, semiconductor industry etc.

In the dustless workshop, FEIDA also produce the food-grade valves. FEIDA food-grade valve is certificated by Food and Drug Administration United States (FDA).
