3 Maintenance

Always use Alfa Laval genuine spare parts.

3.2

Valve Component Inspection

VALVE BODY SEAT(s)
Inspect for nicks and scratches and other signs of excessive wear. Leakage past the seat(s) may result from these types of
irregularities.

VALVE STEM & SEAT(S)
Inspect rubber or PTFE seat(s) for signs of cracking, tearing, checking, or excessive wear. Note: Refer to the TR2-Seat
Replacement section for installation of TR Seats. Inspect stem finish for galling, nicks, or scratches. Leakage may result from
these irregularities.

SPLIT BUSHING
Inspect for signs of cracks, nicks, scratches or excessive wear on inside diameter. A worn bushing will not properly align
valve stem.

O-RING(S)
Inspect for cuts, abrasions, flat spots, or other damage that would cause leakage or ineffective cleaning.
