What is the name of this part?

I realised that one direction you can suck through, and the other you can't. I think there is only two vac hose connections. Although can't remember for sure without looking.
Now, assuming it's simply a valve to control the 'flow' of vacuum, I guessed if it holds a vacuum in one direction it's doing its job. Like a tap.
I then looked further down the line at my problem, and found that the sai switch wasn't sending the valves instructions. So I saved a packet on swapping sai valves, when they only needed the Cappedup™ suck test.
(All of the above could be nonsense, spouted on the Internet as semi-truth.)

Ok, I managed to find some bolts and nuts and I secured both SAI valves. They don't move at all anymore. It made a hell of difference in the way my motor was sounding. Sounds much better now under acceleration.
However, my Service Engine Soon light came on after about 10 miles of driving. I had it scanned and it is P0441, "Evaporative Emission System Incorrect Purge Flow". Now I just replaced the Purge Valve less than 200 miles ago. I also replaced the Fuel cap. Could the SAI valves being tightened down have possible thrown this code? There is no way the new Purge Valve is bad already.
Could this just be a situation where the Code was thrown due to "new" flow b/c of secured SAI valves and when I have the code reset, it will just stay away now?
