Flow control

[glastron23]

the answer is yes and no... what are you using the motor for, is it to propel a wheeled vehicle or is the motor turning a gear box or is it on the end of a conveyor??
you will require one on a wheel motor if the weight of the vehicle can turn the motor with out using the hydraulics and maybe one on a gear box if it has the ability to turn the motor by itself but not really necessary on the conveyor if you are using it on shallow slopes. http://www.princehyd.com/Portals/0/products/valves/catalog/ValvesRd5000.pdf

check on page 7 and it will show the different types of valves. The motor spool connects the 2 ports of the motor when the valve is in neutral so if the motor is turned by the load then it will not hydro lock the motor and damage it.
It you are going to install another valve bank or use an empty valve on your tractor then the flow control is not required, the spool will control the speed. If you want the motor to turn all the time without having to hold the handle then the flow control is the way to go, then you do not require the spool valve as the flow control will act as the spool. We use a lot of these for motor controls where you set and forget it. you can reverse the motors with this unit also.

This is a rock picker project. So I am thinking all that I would need is a flow control.
Where would be the best spot get the hydraulic pressure and return the fluid?

Thanks, Scott

Just plug your motor into the remote outlets, and bungee the lever for continuous operation.

If this is a slow speed hyd motor operation, and you want the motor to stop, just ease the lever back to neutral. Don't let it snap back to neutral.

The manufacture of the picker says to use a flow control. Is it safe to dump the waste oil back to the sump via the fill plug or will that aerate the fluid?

Thanks, Scott

Should be alright.

It will aerate the fluid.

Are you going to be running other functions while having this motor in operation?

Thank you JJ, I will install a flow control and dump back through the fill plug.
I just wanted to be sure because I do not want to harm my tractor.
I will order the control but it will be a while to get it installed because of time and I am fat and getting older.(never thought I would)

Thanks again, Scott

Yes, the rest of the picker and the shuttle on the tractor.

Thanks, Scott

If you will be using the remotes, and it is next to the last valve in the hyd circuit, if you are using a valve upstream of the motor control, then be aware that the upstream valves have priority and can reduce the speed to nothing if all the fluid is being used upstream in the hyd circuit.

As far as aerating the fluid, then have the discharge hose below the level of the hyd fluid.

JJ, am I safe to say that I can tee the return from the motor and the overflow from the flow control together and then back to the remote?

Thanks again, Scott
