Water Filling Valves

GVI water filling unit “triangle”

This water filling unit is developed for mobile bench systems, where a crane lifts or lower the benches to transport them around in the greenhouse. The water filling unit will, caused by the spring band steel bracket, change position when you lift or lower the bench and it will always go back to the original position.​

GVI water filling unit PVC

The PVC Water filling unit is developed for mobile bench systems, where you do not lift or lower the benches, but roll them around in the greenhouse. This water filling unit is also mounted with a spring band steel bracket, which always will make sure that the unit is in the right position.​

  • The Overflow Valve is developed for recirculating systems, where a certain water level is needed on tables or troughs.
  • You can raise or lower the water level by adjusting the 20 mm PVC pipe, which is placed in the valve.
