[ATM] Valve needed - what's it called?

  Once, In Rotterdam, I saw a neat device for dispensing measured amounts of sugar. In fact, it was so intriguing that I purchased one. It has a simple arrangement of a tube centered in the lid and is quite simple in operation. Turn it right side up and the tube fills with sugar, turn it over and it pours the sugar out. I don't remember all the details or when the last time I saw it was but, I'm sure that you can make the device you are looking for from this design. I'll see if I can find it tomorrow and let you know more details if I can.

  Ok all you machinists out there...

I am looking to build a machine to measure my Grit... I am getting tired of measuring by hand...

I am looking for something I can mount on the bottom of a hopper that will control the flow of grit.
I can drive it with a solenoid or stepper.

In my mind I see a metal flap, like a popsicle stick (or larger) that slides in and out of the way.
Somewhat like fertilizer spreaders work.

In fact I have been working with a hand spreader, but I think the gaps around the (plastic) flap are too large.

Oh yes and in true ATM form I want them for as cheap as possible!
