Hydraulic solenoid valve on rear implement

Steve in IN · Apr 22, 2009

Anyone ever added a solenoid valve onto their tractor to prevent a cylinder from moving? JD 3520 pulling a power rake. The rake has a cylinder on it to allow it to angle from side to side. The valve on the tractor allows the cylinder to move from the pressure applied while raking. The valve block on the tractor has already been replaced once.

My thought is to mount a solenoid valve inline to stop the flow. Anyone ever done this? Where do I get the parts and expertise?

Thanks,

Steve

First of all no doubt your Deere is closed center. In a closed center you have high pressure oil on standby. All valves leak. They have to other wise they would be like pipe plugs. This leakage will tend to move to the base end of the cylinder. So it is common to closed center systems.. When I worked for Dana and Dana owner Gresen we had some closed center valves that had internal anti-drift cartridges to help prevent this.So what you want to do is add a check valve. I would think a good brand of pilot operated check valve would fill the bill.

Put a lock valve on the cylinder. I think it is a check valve that that stops the cylinder from creeping. They use them on hyd. top links and crane booms. A solonoid valve is just an electrically operated valve as far as I know. Dave

Punch the link below, then scroll down to "Model RD-1400 Double Lock Valve". It's what you need.
Click on "catalog pages" for more information.

ONE source is Surplus Center.
NO creep

Ny thought is that the cylinder is the problem and not the valve. Piston seal is probably leaking.
