♦ Feature:
1) Using the balancing valve core structure , little axial unbalanced force, large allowable differential pressure, good stability ;
2) Socket duplicity is good, disassembling convenience and easy maintenance;
3) The mental valve core structure for many work situation up to scratch 6 leak standard ,soft sealing structure valve core up to scratch 5 leak standard;
4) The body fluid mechanics theory designed according to such low flow resistance in surface flow ,large adjustable scope, Inherent adjustable proportion is 50:1, the rated flow coefficient increases by 30%,
Actuator adopt spring structure ,highly reduced by 30%,weight reduced by 30%.
