Annual Maintenance: Inspection of internal components (Cont.)
FLANGE (15), PACKING ASSEMBLY/NUT (18):
Visually inspect Flange (15) sealing surfaces for erosion/corrosion. Damage to this area will allow fluid to leak
past the flange during the relieving function. If this surface shows signs of damage, the body should be
replaced. Packing Assembly/Nut (18) should also be visually inspected for wear or missing packing
components that may have occurred during disassembly or usage. It is unlikely that the Packing will be
damaged due its robust design. However, if damage is seen during inspection, it must be replaced with new
packing. Also, inspect male threads for cleanliness and for damage or galling.
CYLINDER (2):
Visually inspect the inside surface of the cylinder for wear or damage. Damage to this surface renders this
component unusable and should be replaced.
