- For nominal diameters of 32 or more and special voltages, the coil shape and specifications are different.
- If you want to have no air leakage, or if you want to use it for well water or river water, please use the WF type series.
- If the nominal diameter is 32 or more and the atmospheric humidity exceeds 85%, use the PF-22Y, 22CY type. (Please contact us for nominal diameters of 25 or less.)
- Please contact us for high viscosity (100cSt or less).
- We also manufacture with a manual mechanism. (Excluding energized closed fluid vapor)
- Refer to page 366 for the lead wire connection method.

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.
