DAN Return Valves

The DAN Return Valves for quick drainage

The DAN Return valves are mounted after the solenoid valves, which are placed on a manifold.

  • When the solenoid valves opens, the water will push the return valve piston down and close the outlet on the return valve.
  • The water will now run to the tables until the solenoid valve is closed.
  • After that, a spring will press the piston back.
  • The water can now run back, e.g. to a reservoir.​
