This valve is doubie-position flow adjustable type. When the air come into the bore P2,this valve is closed.This valve is totally opened when the air come into the bore P1 and P3.When the air come into bore P4,this valve is hale-opened.That rate is half-diminished also means the flowing.
Att:When this kind of valve is working,make sure the inlet Air’s pressure of P3 and P4 is 0.1Mpa bigger than P1and P2.Otherwise,the valve-element cann’t keep balance. |
