"Larson", I would think Ag Chem Solutions would export for the right price.Saw "Lawson" farms on U tube have a few of those fittings last year and like you thought they would be good . He buys his stuff from "Ag Chem Solutions" but no idea if they would export parts to UK ?
Be intrested how you get on .
How about @SimpersTradeCounter for a source?
The handle itself is available from that company to bolt onto the bolted 2” or 3” valve/coupler you may already have.I'm tempted to order one for my self.3" Banjo Full Port Easy-Fill Valve With Carry Handle - VSBHB305FP | FarmChem
VSBHB305FP Eliminates multiple fittings for fill applications Available in 2" and 3" sizes Full flow (full port) design Stubby valve configuration reduces profile Extended coupler prevents handle interference Maximum operating pressure 100 psishop.farmchem.com
Hadn't thought of that, any pictures on how its done?Do you have air on your tractors? If so tap an air line into the 3" pipe work then you can blow the pipe empty into the sprayer. Makes a massive difference to handling a 3" and even a 2".
We have similar set up at moment filling a Horsch 5lt , the 3 inch arag valve is quite a lump and how ever we position it it doesn't seal 100%, needs a 3 cam lever camlock I think, which I see is available but only in a NPT fitting not BSP.Just get a tank fitting and screw the banjo coupling onto where it screws onto tank. I made up something similar the other day.
