suction valves

[Dotk]

Hello to all friends,
I ask you advice because if it is possible it is a road that I would like to travel if not excessively expensive, I am designing a small group in which I need a valve that makes aspiration and then compression dictate in soldons, I would like to exploit the depression that is created in the valves "venturi" we say to capture and then autocentrate the particular that I have to enter, and then use the same valve to shoot in the desired position the body in question, you have never happened to do work of this kind of .unfortunately with the traditional inclined ducts the aspiration is so light that it does not allow me to perform the function I want.
thanks to all and good work:redface:

Thank you so much!
It's what I was looking for, even if I probably still have to call a smc technician to ask him from the economic point of view which system suits me, because from what I saw it is a "pack" for more users and I don't need all this theoretically, the thing that scares me most is the filling of the valves for dirt, I think it can become a problem. .
Anyway thank you again for the very kind answer! :smile:
