Notes for Purchasing Electric Butterfly Valves

With the rapid development of automation, the demand for electric valves, especially electric butterfly valves, is increasing.However, the purchase of electric butterfly valves has a direct impact on the effect of our later use.Therefore, about the purchase of electric butterfly valves, some notes, we wants to share with you in this article.
 

1. Look at the output torque of the electric butterfly valve.Here we need to understand that there are two main structure of valve electric device.One is to configure the thrust disc; the other is not to configure the thrust disc.The output torque is converted to the output thrust through the stem nut in the thrust disc.Direct output torque.The output torque of the electric device shall be 1.2-1.5 times of the maximum operating torque of the valve.

2. Number of rotation cycles of output shaft:The number of rotating rings of the output shaft of the butterfly valve electric device is related to the nominal diameter of the valve, the pitch of the valve stem and the number of thread heads.S is the pitch of the stem drive thread, Z is the number of the stem thread head, H is the opening height of the valve, M is the total number of rotating cycles that the electric device should meet, and their calculation formula is M=HZS.

3. Operating Torque:The motion process of electric butterfly valve can be controlled by stroke, torque or axial thrust.Because the working characteristics and utilization rate of electric valve device depend on the type of valve, the working specifications of the device and the position of the valve on the pipeline or equipment, electric butterfly valve device is an indispensable device to realize the program control, automatic control and remote control of the valve.Therefore, the correct choice of valve electric device is very important to prevent overload.Operating moment is the most important parameter for selecting valve electric device.Usually, the basis for correct selection of valve electric butterfly valve device.

 
If you encounter problems in purchasing electric butterfly valves, you can consult the manufacturers more. Our business specialist of WESDOM Valve will seriously communicate with you the information of operating conditions and related parameters, make low-cost and suitable product proposals for enterprise working conditions, and make reasonable quotations for you.More question, more comparison is the necessary step to select high-quality electric butterfly valve.
