Can anyone explain what this is? I found a food grade, stainless pneumatic gate valve on ebay. It may be just what I'm looking for. I am trying to build a device that allows a powdered candy product to fill plastic tubes. I want to make an automatic valve that opens to allow the candy to flow. Is that a gate valve?
I am continually amazed at the breadth of knowledge displayed on this group. I was just reading the original post imagining the powdered candy running through some type of a hose with a way to pinch it off, and here Ned gives us a link to the exact part!
For what it is worth, Milnor commercial washing machines had a drain valve that may work for you, at least the idea. They used a piece of thin tubing much like inner tube, that was pinched of by a solenoid. The solenoid was connected to a couple of flat bars on either side of the tube. To stop the flow the two bars squeezed togather, pinching the tube closed. Greg
