How To Set A Hydraulics Relief Valve - AskAPT #3

[@ruuman]

These videos are great, really appreciate you taking the time to make them. I had another question, it was about the advantages and disadvantages of vane type pumps over gear, piston and all the other types of pump out there, i really struggle to see any benefit to them.

Guys I'm running a disc marker to mark tramlines in fields. The hydraulic ram putting downward pressure on the discs is operated off the tractor spool. I want to limit the downward pressure applied by the ram though so would a pressure relief valve fitted between hose connection point on tractor and ram allow me to do this? Could you suggest an appropriate type of relief valve please?
