ok never minde i found it

 

Put your switch in parallel with lugs 13 and 14 of KA4. Note that only the solenoid for this one valve will be controlled by your switch. The other valves will not.

the switch that i have to use is a mometary normaly open switch i need the air to stay on until the switch is puled again

 

That's different. You'll have to hook the momentary switch in parallel with lugs 43 & 44 of K4 and hope - best you'll be able to do with a momentary.

If it were me, I'd get another switch - a toggle instead of a momentary.
