Normally Open (NO) vs. Normally Closed (NC) Solenoid Valve: Differences

Solenoid valves are widely used in many industrial applications where automatic control of fluids is required. These valves are used to control water, air, gas, oil, and various process fluids. When selecting a solenoid valve, it is important to consider not only the connection size, pressure, and temperature ratings, but also how the valve will behave when the power supply is interrupted.
