[QUOTE="Hucklebuggy, post: 465723, member: 8504"] The solenoid is most likely a release valve for single acting cylinders. Like described here [url=http://www.surpluscenter.com/Hydraulics/Hydraulic-Power-Units/AC-Power-Units/2-HP-115-230-VAC-1-3-GPM-2500-PSI-SA-POWER-PACK-9-7137.axd]http://www.surpluscenter.com/Hydraulics/Hydraulic-Power-Units/AC-Power-Units/2-HP-115-230-VAC-1-3-GPM-2500-PSI-SA-POWER-PACK-9-7137.axd[/url] But if that is the case, you should only have one port coming out of the pump I think. Maybe the top port was just a tank vent? Is the Cap vented? If that is the case, you should be able to just not power the solenoid at all to run it with a separate valve. The solenoid would only open a port to let the fluid flow back to the tank from port "D". If it were powered all the time you would not build any pressure. So in your case (if it is just a release valve) Plumb ....Port "D" --> Valve "IN" and Port "B" --> Valve "Out". Depending on the flow of the pump you may want to look at a valve that has metering capability, so that you can control how fast your ram moves. I think those wood splitter valves are just on/off/on without much speed control. I think I would have to put a cheap barbed fitting in each port, run a piece of fuel hose from each into a clean bucket (or milk jug) and turn on the pump. Note fluid flow. Power the solenoid, and then turn it on again. Just be sure to have the tank full each time because it will probably drain it pretty fast. Or you could just use shop air and blow gun with rubber tip. Without power to solenoid try to pressure up port "D". It should hold pressure against you. Then power the solenoid, and apply pressure again. It should let air go back to the tank. Check port "B" while your at it, to make sure it allows flow back to the tank in both conditions. [/QUOTE]
