Large butterfly valve with steel plate welded high-temperature manufacturing, mainly for high-temperature medium duct smoke and gas pipelines.

Butterfly valve for shut-off, flow control or throttling of corrosive and abrasive process media in either liquid or gaseous state

A Butterfly Valve is used to control the flow of material through a circular pipe or tube

A butterfly valve is also called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway.

Butterfly valves allow high flows with relatively low pressure loss from the valves, and are typically used for flow control for valve openings from 30 to 70 degrees of full open.

ball valves and butterfly valves have their own limits

In general practice, even though the high performance butterfly valve can be used to replacing ball valve under 600# class (see High Performance Butterfly Valve ), the butterfly valve will only provid
