Anti-Drain Valve (ADV) GR-405-05

The BERMAD Anti-Drain Valve is a spring loaded diaphragm actuated valve that opens upon pressurizing the irrigation system and shuts off drip-tight when the system reaches closure pressure. The BERMAD ADV maintains the main distribution line under low pressure, preventing damage caused by line emptying or fill-up, and enables plot’s irrigation to simultaneously start/stop, thereby contributing to irrigation uniformity.
