I love this. I'm learning more probably than you are. Keep it up.
I have all that and Cross even emailed me some info. I still can't find what I'm looking for. Thanks for the link though.
No biggie, I'll just get a new valve in a bit. I'm more curious than anything now.
Most manufacturers of hydraulic valves only build a basic 4-way function. When they offer a 2-way function, it is usually a 4-way valve with a different spool and the unused ports plugged or piped to tank. Any 4-way valve can perform 2- or 3-way functions in a normally closed or normally open configuration by using the right ports and plugging or draining unused ones.
Well at least you figured out what the problem was! When I fired mine up a couple of weeks ago the cycle time was 56 seconds round trip!!! Talk about painfully slow, I am like you I want some speed so when it money is there I am going to buy either a 22-28 gpm pump. I have a 20 hp motor and a 4x30 cylinder!
John, things are looking up!
I just got off the phone with Cross (very nice people to deal with) and my valve has indeed been converted to a 3 way valve. In other words it is set up for a single acting cylinder. The representative gave me the part number I need and where to find it, she also sent me the parts breakdown sheet.
Now I've just got to wait to get the part.
