Aux hydraulic valve. Optional?

[Jm-baker]

I have seen a photo in the past of a FMD with an optional valve in front of the rear linkage control lever.

Please can anyone who know about how it functions reply. Is it single acting? For a loader or tipping trailer?

Can you still use the tapping point on the side of the standard valve block when it is installed?
Does the position of the rear linkage control valve effect the optional one?

Also, does anyone have one or know where I can get one please?
Any pics?

Thanks

Seems it is single acting, similar to rear linkage valve.

Does anyone know where I may find one?

Here is another one after I realized I may have a DAV:

As you can see from the pictures, The DAV & the 3PH levers are very close to each other. It takes a little getting use to but eventually you remember which one is which. It is a Double Acting Valve but I wouldn't think you would want to use it for a loader. I'm going to use mine for a Hydraulic Top Link but it should work for any double acting cylinder like the rippers on a blade box or a tipping trailer.
