3.The main valve adopts the eight-line proportional valve (BARMAG), which has the variable variable switching function. When switching to the variable mode, the electric proportional valve can load-sensitive the variable pump according to the current action and load, Guide the variable pump output variable, so that achieve the purpose of energy efficiency.
