Product Description

Product Description

A hard sealed butterfly valve is a valve that uses a circular butterfly plate (sealing element) to rotate with the valve shaft to open or close the pipeline.

It is mainly used as a shut-off valve and can also be designed to have functions of cut-off and throttling adjustment. At present, hard sealed butterfly valves are increasingly used in low-pressure large and medium-sized pipelines. 

The butterfly plate of the hard sealed butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When rotated to 90 °, the valve is in a fully open state.

 

The hard sealed butterfly valve has a simple structure, small volume, and light weight, and is only composed of a few parts. Moreover, it can be quickly opened and closed by rotating it 90 °, with simple operation.

At the same time, this electric valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has good flow control characteristics. 

Butterfly valves have two types of sealing: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.
