The flange-type WF-22 series solenoid valve Momotaro II inherits the features that have already been well received from the conventional WF-12 series, and has the same face-to-face dimensions for easy replacement during repairs. At the same time, the durability performance has improved dramatically. In addition, the solenoid valve has a higher degree of perfection in consideration of the environment, such as power saving and clearing the RoHS directive regulation value.

Frequently Asked Questions and Explanations

Is there any problem if the solenoid valve is used (energized) with the valve open for a long time?

The solenoid valve coil has a "continuous rating", so there is no problem even if it is used while it is energized.

The coil of the solenoid valve is hot, is that okay? (There is a video in the answer details)

There is no problem even if the coil part is hot. Please check the video explaining the answer in detail.

If the secondary side of the solenoid valve is a rising pipe, does it flow back?

The solenoid valve is closed by the weight of the valve body and the fluid pressure. Therefore, when there is no inlet pressure and a reverse pressure is applied, the valve opens and backflow occurs. In this case, install a check valve on the secondary side of the solenoid valve.

Please tell me the structure and operation of the solenoid valve. (There is a video in the answer details)

Please watch the video of the answer details.
