Micro 1/4 Plastic Solenoid Valve – Spare part for a Sage Balance Arm
The Balance Arm system works on the evaporation principle. As the moisture evaporates off the mesh arm, the arm tips upwards and at a pre-set position, it switches on the solenoid valve allowing water to flow to the mist nozzles. The mist collects on the Balance Arm and the weight of the water tips the arm down to a preset position and turns off the solenoid valve.
