Recommendation of pressure/vacuum valve manufactures

Recommendation of pressure/vacuum valve manufactures

Recommendation of pressure/vacuum valve manufactures

(OP)
Hey all,

I need some advice and recommendations on what to search for in regards to my project.

The best way to think of my project is to think of inflating and deflating a balloon. I will have a partially inflated balloon of which I need to use a vacuum valve to suck all the air out and leave it flat, after six seconds I then need to re-inflate the balloon to the same size it was originally, and then repeat this process.

The problem I have is that I'm not sure what I should be searching for or who to get it from. I've tried searching for pressure/vacuum valves, automation and control valves, and the such, but not getting anything helpful.

I will be using a DAQ and LabVIEW to control the valves and need to know what I need to achieve this. Links and recommendations will be most appreciated.   

RE: Recommendation of pressure/vacuum valve manufactures

Parker-Hannifin, SMC, Fabco-air, micro-air and about a million others.

Thank you very much for your responses, this is exactly what I need!

If anyone else has any recommendations then keep them coming!

I've been having a look at those solenoid valves and they look very promising. Does anyone else have any other valve suggestions so I can have some comparison?

I started with looking at Festo and their valves but I think it's a bit too automated (and expensive!) for my needs, you guys agree or would you say that Festo may have something to offer?

RE: Recommendation of pressure/vacuum valve manufactures

Too automated?

Open or closed.

Or common-to-A / common-to-B

Basic solenoid valves are essentially commodity items.

By 'too automated' I meant that their uses and features far exceed what I require them to do, if they do what I want at all. Plus, having found a vacuum solenoid valve for £30 they're a tenth what Festo are charging.

Maybe I missed something...  I thought pumps moved fluids...  Valves work as pumps now?

RE: Recommendation of pressure/vacuum valve manufactures

I think searching "vacuum" will take you down the wrong path.  That will get you into the realm of Ultra High Vacuum (UHV) and into vendors like VAT, MDC, and Varian.
