Features
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%,
5.Actuator adopt spring structure ,highly reduced by 30%,weight reduced by 30%.
Bellows seal regulator valve, mobile stem formed completely sealed ,plugging away fluid leakage.
