Electric valve ML-FD type electric valve
There are two types of valve characteristics, ON-OFF characteristics and linear characteristics. ON-OFF characteristics are used for two-position control, and linear characteristics are used for proportional control.
Since this valve is a double-seat valve, there is a leak, so it cannot be used in places where complete closure is required.
Major features
- It has a large flow rate and can be used up to a high pressure difference.
- It is an operating characteristic that does not easily cause water hammer due to valve opening and closing.

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.
