Anti-Water Hammer Hydraulic Valve
It is intended for on-farm irrigation pipelines protection from the water hammer which occurs when excessive pressure keeps growing. To decrease the excessive pressure to the design range this valve performs a quick connection of the pressurized pipeline to the atmosphere and a certain amount of irrigation water is let out from the pipeline.
