Abstract: Aimed at the problem of energy loss existing in common pressure balance circuit controlled by counterbalance valve,two research directions about it’s energy-saving technology were proposed by calculation and analysis for it’s power loss. Based on these two aspects,the three energy-saving models which are gravity conjunction drop, regenerative circuit and energy reclaim were presented and it’s energy-sav-ing performance further analysed in details.
