This replacement solenoid restores electrical operation to a compatible Richdel or Irritrol valve when the original solenoid has failed.
The controller supplies power throughout the watering cycle. When power is removed, the normally closed valve closes.
Use the existing solenoid’s part number and valve model to identify the correct replacement. Check the controller and wiring first, as replacing the solenoid will not resolve a fault elsewhere in the system.
