Matters need attention for disassembling priority valve
1. Plug of pressure mouth is only screwed out when testing pressure; it does not belong to disassembling
range (same principle for assembling).
2. Pull out valve spool slowly, pay attention to protect valve body hole, plug combination surface and thread
from damaging.
3. Check if O ring is deformed, trimmed and aged after disassembling, usually O ring cannot be used again
after disassembling.
4. After disassembling, valve body and spool shall be cleaned with 32# hydraulic oil, check if spool surface
has obvious scratch; do not use spool and valve body if there is scratch.
