Model 132-080 consists of the Robocon Valve (BALEM 130), Hycon Reducing Pilot Valve, Flow Rate Sensing Pilot Valve, and Orifice. In this valve service pressure can be changed automatically as flow rate, so it can maximize running water rate. In addition it is different from electronic valve therefor it doesn't need changing times. Finally Model 132-080 uses high and low pressure pilot valve according to real using flow rate, so it is very efficient.
