The feature of the double eccentric butterfly valve
The double eccentric butterfly valve has a further improved shape on the basis of the single eccentric butterfly valve, and it is currently the most widely used butterfly valve. Its structural feature is that the axis of the valve stem deviates from the center of the butterfly plate and the center of the valve body. The double eccentric effect enables the butterfly valve to be released from the valve seat immediately after opening, which greatly eliminates unnecessary excessive squeezing and scraping of the butterfly plate and valve seat, reduces opening resistance, reduces wear and extends use The position of the life valve seat is improved.

Electromagnetic flowmeter selection, only need to know these three points of knowledge
When selecting the electromagnetic flowmeter, when the medium, temperature and pressure have been confirmed, from the perspective of installation, the first thing that needs to be supplemented is the installation diameter, and then the power supply and output signal. Theoretically speaking, the selection of electromagnetic flowmeters basically confirms which configuration to use after knowing the three elements of working conditions, but for the convenience of later use, it is still necessary to confirm more detailed parameters.

Features of ball valve
The first feature is high wear resistance. The second feature is that the airtight performance is very good. The third feature is that the switch is more convenient. The fourth feature is that it has a long service life. The fifth feature is also the most important feature that I think is the relatively small fluid resistance. It can be said that the ball valve is the valve with the least fluid resistance among all the valves.
