power beyond
power beyond valve has additional port that fluid is directed to when valve is in center (neutral) position. closed center valve has only in,out,a and b and no fluid flows when valve is in center position
Closed centre sytems, (where the valve stops the pumps oil flow completely when in neutral), don't need power beyond as the oil pressure supply is piped to all valves simultaneously. Power beyond is for open centre systems, where the oil keeps flowing, returning to tank, even when no work is being done. Without power beyond, you couldn't add a second or third valve (because the oil, being able to return to tank from the first valve has no resistance. So power beyond plugs the flow in the first valve causing the oil to flow to the second valve, instead of to tank. The second valve (or the last valve if there are more than two), allows the oil to flow to tank, and so complete it's circuit.

Control valve stop valve inch type valve
I have no idea what a power valve would do on a bicycle. Maybe this post belongs in the motorcycle category?
A solenoid valve is a valve controlled by an electrical coil. A spring keeps the valve closed. When power is turned on to the coil, a plunger is pulled, opening the valve.
the contol valve is in the housing the input shaft is connected to the valve
In short, More Power.
cr85r does not have a powervalvle the RM , KX & KTM 85's do have a power valve hope this helps. Jon
The power booster check valve would be located where the vacuum hose is connected to the booster. The vacuum hose is connected to the valve and the valve is inserted into the booster. They are usually made of plastic.
