what does it mean when a valve is posted on ebay as this... "Chief 1 Spool Hydraulic Control 3 Way or 4 Way Valve". i have 2 way cylinders. from what i understand it means i could operate the 2 cylinders for the raise/lower and (1) 2 way cylinder for the dump bucket on my loader? is that a reasonable assumption?

First of all, you would have your cylinders connected in a parallel circuit so they extend and retract at the same speed using one spool in the valve.

Four way, by my assumption, would mean power up, power down, float, and hold.

Would you be able to find a site for the manufacturer of the valve and with a part number, find a spec sheet?

AFAIK, you would need a two spool valve to control the bucket tilt/dump cylinder(s) in addition to the power up/down of the loader arms - or another single spool valve, appropriately plumbed in...

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
