I have a 72 inch Pto snowblower on my ck3510 tractor. The chute moves much to fast up and down as well as sideways. I know I can install a needle valve to adjust the speed but I really don’t want to install four one way valves and bidirectional valves are not at my disposal. If I installed a piece of round stock with a hole drilled through the Centre in the lines where they attach to a threaded coupling, will this work? It shouldn’t be any different than the valve.
Please do not do this you are risking a blown hose and a possible skin puncture which could be fatal.
Please call your machinery dealer and ask them how you go about reducing the relief valve pressure on
those 2 circuits to allow your chute and spout cylinders to react more slowly by reducing the system pressure
which will automatically cause a bypass through each relief valve in the two circuits.
If they do not want to help you please go to the Parker Hanafin home page and look up the dealer locator
and call the closest parker hydraulics dealer to you as they will provide you what you need quickly which
color flow dual directional needle valve for both circuits that mounts on a cylinder port.
These needle valves have female female ports and you will need to buy fittings to connect them to one port of each
cylinder.
The fittings you will need for each cylinder are female JIC(Joint Industrial Council) to male NPT to connect to the fitting
on the cylinder barrel and the other end of the color flow valve is an NPT male to JIC female fitting.
So you need two of the color flow valves and four fittings to solve this if your dealer will not help you.
