Unloader Valve

Would this unloader that is rated for an 8gpm machine be compatible with my 4gpm machine, as long as the fitting sizes are the same? and could I use a normal brass nipple to connect it to my machine or do the fittings need to be rated for the higher PSI too? Thanks!

If it’s a pressure unloader it’s the psi that will matter, but most of the ratings are maximum gpm or psi a lot of times.

Your best bet is to call the vendor.
