optimization suggestions
*When designing control schemes, try to choose normally closed (NC) type as much as possible. If the opening time of the solenoid valve is long and the closing time is short, choose the normally open (NO) type.
*If the fluid contains impurities, a filter screen (≥ 60 mesh) should be installed in front of the valve.
*The direction indicated on the valve body must be consistent with the direction of medium flow.
