Hello all,
I have a question on the mcmaster .5" QEV, part number 6646K25.
On the picture for this part, There is a picture of the valve, with one arrow going into the port, and a arrow from the one coming out. What connect where?
Does the chamber connect to the port that depicts the arrow going into the valve, the barrel from the outcoming arrow, and a pneumatic valve on the exhaust? Where do you charge the chamber from?

Look at the diagram on the bottom right of the page, that should tell you what you need to know.
