This Danfoss solenoid valve is designed with a nominal diameter of 1/2 inch and features a normally closed (N/C) operational configuration. The valve is constructed to control the flow of fluids or gases in a system by opening or closing when electrically energized or de-energized, respectively. Its 1/2 inch size refers to the nominal diameter of the connections, allowing for standard integration within corresponding piping systems. The normally closed designation indicates that the valve remains closed when power is not applied, ensuring a fail-safe operation in the default state.
