| Operations Applied with three way solenoid valves |
| Normally Closed (NC) |
Normally Open (NO) |
Universal (Univ) |
| When the solenoid valve is de-energized, the pressure port is closed and the exhaust port is connected to the cylinder port. When the solenoid valve is energized, the exhaust port is closed and the pressure port is connected to the cylinder port. |
When the solenoid valve is de-energized, the pressure port is connected to the cylinder port and the exhaust port is closed. When the solenoid vlave is energized, the pressure port is closed and the cylinder port is connected to the exhaust port. |
This allows the solenoid vlave to be connected in either the Normally Closed or Normally Open position ... or to select one of two fluids or to divert flow from one port to another. |
