Hey guys, I'm working on my Sunflower field cultivator. It is an older one, has wings and 4 lift cylinders. The depth stop valve was not internal to the cylinder, it was an external device mounted inline before the first lift cylinder. It had gotten rusty and ruined it before I got it, and leaked a lot of oil, so I had just bypassed it for the time being. Parts for the depth stop are no longer available, and a newer style depth stop valve is about $1500 from Sunflower. So I found this Parker cylinder stroke control valve for $60. I think it will work just fine, but I have a question on my plumbing. All of the cylinders are plumbed in a loop essentially. The one hyd line runs into the bottom of the first cylinder for lift, then comes out the top of the same cylinder and goes into the bottom of the next cylinder. And so on, until it ends with the last hose coming out of the top of the last cylinder going back to the tractor. Could I use this valve inline at the inlet to the first cylinder of the group like the last one was, or will I have to split it between the first 2 lift cylinders as shown? Here's a picture of the valve I plan to use. Thanks guys
