Frequently Asked Questions and Explanations
What is overload protection?
This prevents the motor from burning if the motor exceeds the maximum allowable temperature for some reason.
What is a spring return type? (There is a video in the answer details)
It is a mechanism that winds the spring at the same time as the valve opens when the power is turned on, and closes the valve by the force of the spring that winds up when there is a power failure. (In the case of valve open type when energized)
Do you make a spring return type three-way valve?
We do not manufacture spring return type three-way valves.
