Hydraulic Valve

Postby ajhbike » Mon Oct 16, 2017 6:34 am

Trying to understand the Hydraulics on the remote system (cylinder lifter on the back) because I don't have a lever to work it yet. When the rocker pushes on the valve "button" the cylinder lifts when the lever is moved to engage it. Does the lever need to be stationary once moved? And to lower the cylinder the lever disengages from the button?

In other words....it is an open hydraulic system?

At rest, the lever is in a neutral (center) position. When moved one direction, the cylinder will move one way and continue to do so until the lever is returned to the neutral position. When the lever is moved the other direction, the cylinder will move the opposite direction until the lever is returned to the neutral position.

So that rocker is both picking up the booted valve switch and pushing it down? So it is different than the Cubs?

The Cub Touch Control has mechanical linkage between the piston, valve, and lever to automatically move the valve back to the neutral position when the piston reaches the position that corresponds to the lever position. The lever is a position control rather than a motion control. The valve has 3 operating positions, neutral in the center and forward/back to move the piston the corresponding direction.

Not sure what you mean by closed system.
Closed loop - feedback for positional control - yes for internal Touch Control valves.
Closed center valve - valves block flow in neutral position - yes for Touch Control internal valves, don't know on the remote valve pictured above.
Closed system - unvented reservoir - yes for Touch Control unless changed by some remove valve additions.

I just looked at the valve and I can't understand how it can be in a neutral position....the valve button gets pushed down part way or all the way but there is only the one valve button...no other valve to depress to counter the down stroke. It seems it is pushed down and stays where the lever pushes it to and to change cylinder direction I reverse the downstroke by letting up on the button. I appreciate the help, but it isn't sinking in

When you walk up to the tractor, the valve should be in the neutral position. Pushing the lever one way will push the valve down to move the cylinder one way. Pushing the lever the other way will pull the valve up to move the cylinder the other way. Let go of the lever and the valve should pop back to neutral.

Ah....because it isn't really a rocker arm like on the cub starter....It is connected to the valve button. Got it. Incidentally, part of the lack of understanding is that I have no lever. I only have the connecting rod from the lever to the valve button...I am going to buy, adapt or fabricate the lever and bracket. Thanks

You might check with JP Tractor Salvage, to see if they have the parts you need.

I tried them. Basically, any lever with a bracket for the light bar can be adapted. Not many salvage yards up here in CT.

To work effectively, I would think the lever/bracket/rod combination would need the correct geometry.
