1 Direct Acting Normally Open Solenoid Valve

Low Power Consumption Direct-Acting NO Solenoid Valves

The electromagnetic force in direct-acting solenoid valves is applied directly to the valve core system. These valves rely solely on electromagnetic force and a reset spring for their operation, making them highly reliable and unaffected by factors such as the pressure difference of the medium.

Direct-acting normally open solenoid valves are valves that stay open when there is no power supply.

  • Default State: By default, the valve is open, suitable for applications where fluid flow must be guaranteed in the event of a power loss.
  • Safety: In the event of a power outage or an emergency power cut, the valve remains open, which is critical for certain safety systems.
  • Simplicity and Reliability: These valves have a simple structure, are easy to maintain, and operate reliably.
  • Energy Consumption: They maintain media flow when de-energized, resulting in lower energy consumption during normal operation.
