PRINCE AUTO-CYCLE CONTROL VALVE Brand new PRINCE. Special Auto-Cycle valve allows operator to completely cycle (out and back) a double acting cylinder by only one handle movement. Ideal for log splitter applications Both levers are pulled out to detent position, cylinder extends and at end of forward stroke one lever automatically returns to neutral and cylinder reverses. When fully retracted second lever returns to neutral. (3 work ports are used, two are tied to together and then run to rod end of cylinder, third connects to base end of cylinder). SPECIFICATIONS
Spools Special For 1 DA Cylinder
Double pressure relief detent
Flow Max 25 GPM
Pressure Max 3000 PSI
Relief valve Adj.1500-3000 PSI factory set @ 2000 PSI
can this valve be used to power another downstream valve
A: No, it cannot. We offer a Power Beyond capable version (9-6587-PB) for a few dollars more.

Will this valve work with the dynamic 28 gpm 2stage log splitter pump. This valve it says is rated only for 25gpm and pump puts out 28gpm. Or is there another auto cycle valve i can use
A: While there may be a slight pressure loss and minimal heat buildup from any restriction through the valve, other customers have used those two items together and have not reported any failures from doing so.

I have a homemade firewood processor that I want to use this valve on to auto cycle the splitter. The processor is powered from the high flow auxiliary hydraulics on a skid steer. The skid steer provides 30 gpm at up to 3,000 psi. I'm planning on splitting the incoming lines with your Divider Valve (Item 9-1048-C) to give me 15 gpm going to the auto-cycle valve/ splitter and 15 gpm going to the other directional valves (log conveyor, log lift, etc.). All the directional valves are open center. Therefore, the pressure is very low until a valve is activated. If I use a valve on the other inlet line (downstream of the divider valve) while the splitter is cycling, will the detents be affected by the drop in line pressure? I assume that the Divider Valve does not regulate the pressure, it simply divides the flow evenly, is that correct?
A: Item 9-1048-C is a pressure-compensated proportional flow divider with a 50:50 ratio. The output flows should remain equal even with very different pressure loads, as long as the input flow is within the valve's stated range. Keep in mind if your skid steer's hydraulic system is a closed center system, operating open center valves on it will cause the pump to work constantly and overheat the system in a relatively short period of time. If your skid steer is an open center type it shouldn't be an issue.

I have a 28 GPM DYNAMIC 2-STAGE PUMP Item number 9-7971 with this spool. And on the return stroke, it broke the 1 inch plate off the 3 inch cylinder shaft. Is there a way to get the detent to release with less pressure on the return cycle?
A: The detent release is controlled by the main relief valve pressure setting. Unfortunately there is no way to have different pressure setting on the two different directions of movement.
