Pneumatic Regulating Valve For Water, Steam, Oil, Acid, Gas

Size:DN20~500 1''-20''Inherent Rangeability:50:1Body Material:WCB,304,316,WC6,WC9,Ti,Ni,Hastelloy,Monel etc

 

 

 

 

Feature:

 

Using the balancing valve core structure , little axial unbalanced force, large allowable differential pressure, good stability .

Socket duplicity is good, disassembling convenience and easy maintenance.

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.

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%.

ZJHMW bellows seal regulator valve, mobile stem formed completely sealed ,plugging away fluid leakage.
