Hydraulic control valves are typically "wired" in series. Control valves in the neutral position, centered, permit hydraulic fluid to flow through the valve, from the pump to the reservoir.outdoors4evr wrote:I don't understand why you couldn't add another valve (like the one shown above) in parallel with the current valve?
If you "T" the hydraulic fluid prior to two or more valves. All of the fluid will flow through the control valve(s) in the centered/neutral position and not through the control valve moved into the work position.
