Note:
The solenoid valve is mainly divided into normally open, normally closed, inlet valve and drain valve. The explanation is as follows, buyers must choose according to their own requirements, so as to avoid unnecessary losses caused by unsuitable purchases.
1. Normally open‑refers to closing the valve when energized
2. Normally closed‑refers to opening the valve when power is applied
3. Water inlet valve‑‑refers to the water pressure environment of 0.02‑0.8MPa, where there is water pressure
4. Drain valve‑refers to the water column used at the working pressure of ≤400mm
