5. To remove contaminated hydraulic fluid, refill the system and repeat steps 3 and 4.
Note: To prevent contamination use only one type of hydraulic fluid in the pressure station.
6. Pressure Relief Valve (PRV)
6.1 Introduction
Use a pressure relief valve (PRV) to limit the pressure you can apply to the equipment under test.
The PRV is factory set to operate at the maximum pressure specified on the label (on the plastic
cap).
If the pressure in the pressure station is more than the PRV relief pressure, the PRV controls a
slow release of the unwanted pressure. The correct PRV helps prevent overpressure and
damage to the equipment under test. To adjust the PRV, see Section 6.3.
WARNING Pressurized gases and fluids are dangerous. Before you connect
or disconnect pressure equipment, safely release all pressure.
CAUTION To prevent damage to the pressure station, do not let dirt get into
the pressure mechanism. Before fitting the pressure relief valve (PRV), make
sure it is clean.
