Pressure Regulating Valves (PRV)

Proper lubrication is critical to compressor frame operation. The oil type, viscosity
grade, cleanliness, flow, pressure, and temperature of the oil are important factors.
Key components in the lubrication system are the internal or external oil pressure-
regulating valves (PRVs). The external PRV controls the output pressure and flow
by recycling excess oil volume from the pump outlet back to the crankcase. The
internal PRV acts as a backup pressure regulating valve.
The PRV is a pressure regulating valve not a pressure relief valve.
In normal operation the internal PRV is partially open, bypassing oil back to the
crankcase. Adjust the external PRV on the H302 compressor frame during normal
operating conditions to maintain oil supply pressure to the main bearings (see
"Figure 12").
