With the rapid development of electric butterfly valves, electric butterfly valves are more and more widely used in practical applications, and win the favor of customers with excellent quality and perfect after-sales service. There are two connection modes of electric butterfly valve, one is flange type, the other is wafer type. The electric butterfly valve is suitable for occasions requiring flow regulation. The pressure loss of butterfly valve in the pipeline is relatively large, so when selecting the electric butterfly valve, the impact of pressure loss on the pipeline system and the solidity of pipeline medium pressure should be taken into account.

3. The output torque and speed output torque value of electric equipment is one of the important skill parameters of electric equipment, and also an important parameter to be selected in the application. If the output torque of the selected electric equipment is too large or insufficient when assembling electric valves, it is not advisable. Due to the general situation, the electric equipment manufacturer needs to test and adjust the output torque value when the products leave the factory, which is relatively accurate. If excessive output torque margin is selected, electric valve will have great potential danger. Once control and maintenance failure occurs, valve damage (valve stem twists, valve body cracks) will be easily formed, which is very easy to cause pipeline system incidents. Therefore, it is not advisable to select excessive output torque margin. If the valve cannot be opened in practice, it is also due to unreasonable selection.
