Depending on where the valve is plumbed into the hyd system,(open center) you may want to add the power beyond sleeve option and 3rd hose. If the valve is located upstream of more hydraulic functions,(3 pt., aux. hyd remotes, or other features) and you do not add this feature, the valve will eventually start to leak at the spools. The hyd fluid will back up inside the loader valve, push the spool o-rings out against the back-up washers and bend the handle bracket causing the leak. Plumbing the loader valve downstream of everything, i.e. into the remotes at rear of tractor does not require this extra bit of expense. The screw under the acorn nut is the relief valve and can be set with a 3000 psi hyd guage by backing the screw out and screwing it in slowly to desired setting. Usually a depending on tractor, loader, cylinder, hoses, tractor hyd relief valve setting, 2000-2500 psi. Very few new loaders are plumbed properly because of the extra cost in power beyond. But it is well worth the extra effort in ease of operation and cleanliness. Freeing up the remote is worth the expense in itself.
