Butterfly Valve Applications and Selection Guide for Your Project

Butterfly valves are used for pipeline shut-off, flow regulation and system isolation in fire protection, water supply, HVAC, wastewater treatment, municipal utilities and industrial piping systems. For a project buyer or contractor, the key question is not only where a butterfly valve can be used,

0f63ca65-094c-4b3b-b645-0492d2c962f3.jpg

Why use butterfly valve instead of gate valve?

Butterfly valves and gate valves are both used for pipeline shut-off and flow isolation. In many water, fire protection, HVAC, and utility pipeline systems, both valve types can open or close the flow of water or other compatible media. The right choice depends on pipe size, installation space, oper

Grooved Butterfly Valve with Tamper Switch_副本.jpg

How Does a Butterfly Valve Work in Water, HVAC and Fire Protection Systems?

When you use a butterfly valve, you can control liquid or gas flow with a simple turn of the handle. The valve has a round disc that spins inside the pipe. You can open, close, or change the flow fast by turning the disc. Many industries pick a butterfly valve because it is small, light, and saves m

法兰对夹蝶阀1.jpg

What are the different types of butterfly valves?

You can find a few main types of butterfly valves. These are concentric (zero offset), single offset, double offset, and triple offset. These valves also sort by seat material, connection type, and actuation method. When you pick a valve, you should know these differences.
