optimization suggestions
*When designing control schemes, try to choose normally closed (NC) type. If the solenoid valve has a longer opening time and a shorter closing time, choose normally open (NO) type.
*The fluid contains impurities, and a filter screen (with a mesh size of ≥ 60) should be installed in front of the valve.
*The direction of the valve body marking must be consistent with the flow direction of the medium
*The working pressure of coils providing special voltage may vary, please be sure to consult our factory first.
