Hi I went to look. It has 1 large cylinder in the middle. I replaced the hose that connects to the very bottom of that cylinder. Inspected the cylinder no dents. Check the rollers if that's where the hoes goes around on top and it seems to be ok. Is the valve you're speaking of internal or external on the cylinder?
