For single core, when the medium is open flow type, the valve stability is good; when the medium is closed flow type, the stability of the valve is poor. The double-seat valve has two valve cores. The lower valve core is in flow closure and the upper valve core is in flow opening. In this way, when working with small opening degree, the flow closing valve core is easy to cause vibration of the valve. This is the reason why the double-seat valve cannot be used for working with small opening degree.

In the pipeline system, the valve plays a vital role. When it is necessary to connect or cut off the medium in the pipeline, the cut-off valve can play its role. Through the lifting movement of the valve flap, the cut-off valve can realize the complete opening or closing of the medium, so as to realize the precise control of the medium circulation in the pipeline. However, it is worth noting that the shut-off valve is not suitable for use as a throttle device. Although the lifting movement of the valve can adjust the flow of the medium to a certain extent, this method is not accurate and is easy to cause damage to the valve itself.
