remote control for sandblaster

[andrex88]

hello to all, I would like to ask you for help to understand and realize a scheme for a pneumatic or electro-pneumatic remote control, my sandblaster and free jet a cb-24, I saw that they sell kits but they are too expensive for me and therefore I would like to realize it, to do some jobs that I might need to do interruptions that I could not at the moment, but also understand its operation. Meanwhile looking at the various kits need these automatic valves, there is one normally closed for air input, and a normally open for the vent of the tank, I would like to ask with some of you if you know this type of valves in photo, more or less how much they can cost and where they are available. thanks in advance

So... .
we do something simple but effective
read what you wrote, correct the horrors of spelling and grammar, sum up the ideas and make them clearer, re-expose the concepts and then we talk about it
All this because, personally, I didn't understand a damn thing you wrote!

Hi.

hi I hope to be clearer then, so I should realize a remote command for the sandblaster, practically so that I can stop the sand jet when I have to stop the sandblasting cycle, the problem that around they see kits to turn a simple free jet sandblaster into remote control. but these kits cost a lot, so I'd like to make it happen to me, buying only essential things. but I still have to understand if I should realize the project with valves controlled electrically or pneumatically. Thank you.

already better.. .
if you use more points and less commas the sentence will become simpler and intelligible.
now, the questions are as follows:
Should the valve stop only the air flow or even the sand?
How are you going to command this valve? with a pedal? Button? crank? Switch?
