Shanghai Dongfeng Electric Butterfly Valve Manufacturing Co., Ltd. There are many types of fans. We generally select the appropriate fan butterfly valve electric butterfly valve for you according to the installation method, operating weight, weight, speed of fan, and installation quantity of electric butterfly valve.

If it is a special case, it is in the case that the fan is heavily weighted: for example, a 400 kg fan needs to be installed with four electric butterfly valves at the installation positions 1, 2, 3 and 4, of which the installation position 1 is relatively heavy, accounting for an estimated 35% of the total equipment weight. How to select electric butterfly valve. 1 Position: 400 * 130% * 35%=182kg 2, 3, 4 Position: 400 * 130 * 65%/3=112kg Fan speed determines the natural frequency of butterfly valve electric butterfly valve; The electric butterfly valve of butterfly valve shall be selected according to the frequency ratio of at least three times.
