Description:
The anti-drain valve can effectively control upside-down micro-spray accessories to ensure they do not drip when the valve is closed and the water is shut off, thus effectively protecting crops. When system pressure is greater than 0,7-1,0 bar, the water volume begins to spray through the micro-nozzle of the anti-drain device. When system pressure is less than 0,4-0,8 bar, the water flow stops and the micro-sprinkler no longer sprays water through the anti-drain device.
