hydraulic valves, open center/closed center conversion
hydraulic valves, open center/closed center conversion
(OP)
I am interested in using a constant displacement pump(gear-type) and want to be able to have a system that runs open center when not in use and converts to closed center whenever any of the valves is actuated. This way we dont have fluid spilling over a pressure relief(generating heat) and yet we can operate multiple circuits at once like a closed system does. I would prefer a straight mechanical valve for simplicity. Is there any valve that would accomplish this?
