Anti-Drain Valve (adv) IR-205-05 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. Features and Benefits ■ Spring Loaded Elastomeric Valve □ Self operated □ Range of closing springs ■ Plastic Globe Hydro-Efficient Valve □ Unobstructed flow path □ Single moving part □ High flow capacity □ Highly durable, chemical and cavitation ■ Flexible Balanced Diaphragm & Seal □ Fully opening □ Secured drip-tight closing ■ User-Friendly Design □ Simple in-line inspection [1] [3] [3] Typical Applications ■ Plain Plots with Sloppy Margins ■ Downhill Sprinkler Lines ■ Hillside Irrigation Machines [1] BERMAD Model IR-205-05 opens upon start of irrigation and shuts off drip-tight when irrigation stops, maintaining main distribution line under low pressure, and preventing damage caused by line emptying or fill-up.
