Drainage valve to be used for automatic tube emptying after irrigation. The valve allows the water to drain when the pressure drops below 0.25 bar, whilst it shuts automatically when the pressure is above 0.4 bar.
It must be installed at the lowest point of each individual sector and an in- spectable well fitted, well-drained sump with gravel. In very long sectors the fitting of multiple drainage valves is recommended.
