What is a double offset butterfly valve

The double offset butterfly valve is gradually improved by the ordinary butterfly valve to adapt to different working conditions. The earliest butterfly valve structure is mainly the center door panel structure, similar to the adjustment butterfly valve, that is, the axis of the valve stem and the butterfly plate coincides with the center of the valve body pipe.

What can butterfly valve be used for

Butterfly valves are used in a wide range of applications and are suitable for flow regulation. Because the butterfly valve has a large pressure loss in the pipeline, it is about three times that of the gate valve.

Problems encountered when using soft seal butterfly valve

The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°.

Difference between double and triple offset butterfly valve

The double offset butterfly valve is characterized in that the shaft center of the valve stem is offset from both the center of the disc and the center of the body. The double offset effect allows the disc to be quickly disengaged from the valve seat after the valve is opened, which greatly eliminates unnecessary over-squeezing and scraping of the disc and the valve seat, reduces the opening resistance, reduces wear and improves the seat life.

Difference between offset butterfly valves

The offset butterfly valve is divided into single offset butterfly valve, double offset butterfly valve, and triple offset butterfly valve. A butterfly valve whose valve stem axis is at the same time deviated from the center of the disc and the center of the body, and whose sealing pair is a slanting vertebra is called an offset butterfly valve.

Development of triple offset butterfly valve

The superior performance of butterfly valve is closely related to their constant eccentricity, evolution and development. In order to meet various working conditions, the butterfly valve has experienced the evolution from concentric to single eccentricity, double eccentricity and triple eccentricity.

Centerline butterfly valve vs offset butterfly valve

A butterfly valve is a valve in which a closing part is a disc that rotates around the valve shaft to open and close, and is mainly used for cutting and throttling on the pipeline.

Butterfly valve function

Compared with other valves, the butterfly valve has a simpler structure. It is smaller in size, lighter in weight, and has fewer components. It relies on several key components to form a butterfly valve, but it has achieved better use.
