Slowing down hydraulic chute rotation on snowblower

[joe04785]

Hey all, I got a question about slowing down the rotation on a snowblower chute that is hydraulicly operated. I have been looking at installing an in line valve to slow the rotation of the chute. My question is do I need one in line valve or two in line valves, one for each line?

Maybe this valve will work for you. Controls flow is both directions.

3/8 NPT 8 GPM PRINCE WNV-600 NEEDLE VALVE

I agree with J. J. (other comment) The only way to reduce speed or oil flow is by a valve (2 ways) or insert a smaller spooler in each line.

The needle valve is simply a hand adjustable orifice so it works in both directions.

FYI - You will probably notice that the cylinder is faster retracting than extending. If for some reason this is not acceptable and you want to adjust the speed for each direction separately it is possible, but more complicated. Let us know and we can give a solution or two.

I put on 2 flow control valves. As the old expression goes " when in doubt meter out " When I am running the snow blower the engine is at rated PTO speed and the chute would really be moving to the point it could damage itself. If I remember correctly I used one way flow control valves. You get a difference in speed due to the rod diameter of the cylinder and you probably already know that. If you need the exact pt. number let me know but I used 2 because of the speed differential. Later

I have a question on the same issue.
My Massey GC2310 piping is 1/4 NPT so I was planning to get this:
1/4 NPT 5 GPM PRINCE WNV-400 NEEDLE VALVE
Does this valve require proximity to the motor or can I place it in-line at the other end of the hose where it would be convenient (i.e. Needle Valve>elbow>quick coupler)

 

[J_J]

That should work.

 

[timbrehse]

That should work.

At either end of the hose?

Yes. -------------------

Is your chute rotation via a hydraulic motor or a cylinder? If a motor you may want to install a flow control in each line metering flow into the motor and free flowing out of the motor. If just using a single flow control you will be pressurizing the shaft seal while rotating in one direction and could potentially blow the shaft seal out.
