In movement ability
Because the electric gate valve can only be fully opened and fully closed, the flow resistance of the electric gate valve is smaller when it is fully opened;
When the electric butterfly valve is fully opened, the thickness of the butterfly valve creates resistance to the circulating medium. In addition, the opening height of the electric gate valve is higher, so the opening and closing speed is slow; the electric butterfly valve opens and closes quickly.
In function and use
The electric gate valve has good sealing performance, so it is mostly used in pipelines that require strict sealing and do not need to be opened and closed frequently. The electric gate valve cannot be used to adjust the flow rate. In addition, because the opening and closing speed of the electric gate valve is slow, it is not suitable for pipelines that need to be cut off urgently.
The electric butterfly valve can not only be used for cutting off, but also has the function of adjusting the size of the flow rate. The butterfly valve opens and closes quickly, and can also be opened and closed frequently, which is especially suitable for use in occasions that require quick opening or cutting.
The electric butterfly valve has smaller dimensions and lighter weight than the electric gate valve, so in some environments with limited installation space, it is recommended to use a more space-saving wafer-type butterfly valve.
In price
Under the same pressure and the same caliber, the price of electric gate valve is higher than that of electric butterfly valve. However, the caliber of electric butterfly valve can be very large, and the price of large-caliber electric butterfly valve is not cheaper than that of electric gate valve.
