lift valve Types
 

I would like some clarification please. Types of implement lift valves? What makes one STACKABLE or NON-STACKABLE. Were the stackable ones optional or model specific? Thanks

Photos would be good!!

HA! I beat you to it Duke.:biggrin2:

Hydraulic valves are mostly made out of cast iron.

Stackable valves are a stacked assembly of the
inlet section
work section
outlet section

Non stackable valves are a 1 piece casting that has been machined to include the ports and features of the stackable valve in one casting.

By simply using longer bolts, the stackable valve can control more cylinders.
inlet section
work section
work section
work section
outlet section

The only limit is the strength of the bolts holding the sections together.

Non stackable valves have fewer places to leak, and usually cost a little less.


There are other features available to each valve, but, these are the features that pertain to Cub Cadets.

But I still win!

:TTWWP:

Duke, show us your loader valve!!

Yea Duke give it up! :popcorn:

From what I understand, the valves on the 1864 model/series tractor was a stacakble style. As far as I know, all of the valves up to the 1712/1812 series were not stackable - they were cast. I am not sure on the valve styles on the supers. MattG would have a better idea, I have seen him talk a little on this topic on the forum somewhere...

I'll get pics tomorrow for you slackers!

The only CC tractors that had the stacking valves are the cyclops tractors, 1990-1996, and possibly the 3000 series after, as well. I've never had a 3000 series so I can't say for sure.

I have seen the newer valves (3000 series?) from what I see there a machined block and use an "o" ring seal. Do the cyclops use the "o" rings as well? I am thinking a cast type w/threaded fittings, I would like the ability to add circuits without re-doing the existing valving. I guess I could use an aftermarket/off brand setup with multiple ports,as seen on a post here. Is there a limit to how many valves can be stacked?

How much money you got??:bigthink:
