Mini Anti-Drain Valve, The Mini anti-drain valve can prevent the water from leaking. When the pressure in the system is high, water will flow through the mini anti-drain valve. When the pressure is low, the flow of water will be stopped at the valve to prevent leaking When the water pressure is 0.7-1.0 bar, water will flow through the mini anti-drain valve. When the pressure becomes 0.6 to 0.7 bar, the mini valve will prevent the sprinkler/dripper from dripping  The valve opens upon pressurizing the irrigation system and shuts off drip-tight when the system reaches closure pressure That means no water will leak once the irrigation system is closed This anti-drain valve will open when water pressure is higher than 0.7 Bar Please buy 4mm Connector pins and feeder tubes as per requirement  Even the air will not come out if tested with mouth or do not exceed 0.8 bar.
