Auxiliary pressure

[Skid_der]

I be been looking up hydraulic pressure specs for auxiliary attachments..websites I found talked about hydraulic pressure at loader. 15.6 gpm @ 3300 psi. Now is that the pressure at the bucket or at the auxiliary ports .?? Do they share the same pressure?? Thank you

If they state the pressure is that, the pressure will be that figure at the aux ports and cylinders. They generally use one relief vlve for the entire hydraulic system. The only difference is they can install a higher value relief in the lift circuit to prevent the cylinders being over loaded if you curl, putting higher pressure on them. This prevents the cylinder on hose failing.
