Flow Rating for Valve Bank in PB Circuit

Spudland_Dave · May 7, 2009

So I think I've found an affordable 12v Solenoid controlled valve bank to use in my PB Circuit...before buying it I'd like to know what exactly I should be looking for in terms of GPM Flow, etc...

Tractor its going on is a 3520

Good Morning. I'm not a hydraulics expert but I spent the night at a Holiday Inn Express

I was looking at the specs for the 3520 and it lists a total flow of 13.9 GPM and a valve flow of 8.6 GPM. I would think that you would need a valve rated for at least the 8.6 GPM since the PB circuit is flowing through the valve and you would not want to impede the flow for any downstream application.

Thats my biggest question....what number should I use? 13.9 or the 8.6?

Your tractor has two pumps, one is dedicated to the steering and the other for implements. The 8.6 number is what you want to use-so a valve rated at 10 GPM would be perfect.
