There is two critical time in the operation of a pipeline. During filling, air occupied in the empty pipe must be evacuated ahead of the incoming liquid in a controlled and efficient manner so that surge and water hammer can be minimized and liquid can completely be filled in the pipe. During draining, whether planned or unexpected, air must be admitted into the system to replace the out flowing liquid to avoid excessive vacuum and possible pipeline damage. Air release valve are designed to release accumulated air pockets from the system, while pipelines are pressurized. Air pockets cause increase of energy consumption because pumping operation will be at higher water heads to overcome pressured air. Air release valves have function to protect high shock and surge pressure, water hammer and liquid overflow from fresh or sea water pipelines. PROSAVE Valve can assure to provide low maintenance cost of pipelines and pump systems.
