The oil pressure valve limits the pressure in an engine's lubrication circuit, bleeding oil back to the sump once the pump delivers more than the bearings need. It protects the filter and the seals from the high pressure a cold, thick oil produces at start-up. Units are ordered by opening pressure — this group runs from 5 to 7.5 bar — and by port thread.
