What is a two-speed electric valve?
Thread Content
As the title suggests, I came across information on dual-speed electric valves – what kind of valves are these? What does dual speed mean? Seeking advice from experts
A device is driven by two motors, with the two motors having different speeds. We don’t need this kind anymore; there are variable-frequency ones available
Wouldn’t it be simpler to use a two-speed motor for driving?
By controlling changes in the wiring of the motor coils through external contactors, the number of poles of the motor can be altered, allowing a single motor to have two speeds, three speeds, etc.
