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 openrefers to closing the valve when energized2. Normally closedrefers to opening the valve when power is applied3. Water inlet valverefers to the water pressure environment of 0.020.8MPa, where there is water pressure4. Drain valverefers to the water column used at the working pressure of 400mm
