Electric butterfly valve
Thread Content
There is a pipeline that originally had an electric butterfly valve with a DN100 size; now the diameter of this pipeline has been changed to DN150. I would like to ask whether it is possible to replace the DN100 butterfly valve with one of DN150 size, while continuing to use the existing electric actuator In other words, when the pipe diameter increases, the electric actuator remains unchanged; only the valve is replaced. Is it feasible?
I think there’s enough drive for it; it depends on how strict you are about leaks. If not too strict, it should work fine, but if you’re strict, it’s better to replace them all together
Check the water pressure; if it’s at normal pressure, that’s fine – perhaps the valve opens a bit slowly
Well, the answer above is correct; the key factor is pressure. If the pressure is very high, your electric butterfly valve might burn out its small motor due to excessive load
What was said upstairs is also correct! Pressure is very important! As the diameter increases, the torque required of the valve also increases. If an actuator that is too small is used, it will be difficult to operate the valve! :) Of course, some manufacturers produce valves with low torque; in such cases, you can use an actuator designed for a DN100 diameter! :) :) QQ: 928976489
First, determine the opening torque of the DN150 valve (this value is provided in the valve manufacturer’s specifications, but it usually does not include a safety factor; this factor is not necessary to consider if the fluid is water). Next, find out the rated torque of the electric actuator and check whether it is greater than the valve’s opening torque. If it is, then the actuator can be used; otherwise, it is recommended to replace it. It is also necessary to verify that the flange on top of the valve matches the mounting flange of the actuator, otherwise installation will not be possible, and custom connectors will be required
