b.
Line relief valve regulates pressure spikes from either implement pump or any unusual outside forces acting on
work tool. When pressure is higher than line relief valve setting, relief valve opens. This allows high pressure to
return to hydraulic tank. Line relief valves prevent high pressure from damaging any hydraulic system compo-
nents.
