8. MAINTENANCE AND CLEANING

Normally, purging the valve with appropriate flush material or solvent after use is sufficient for
cleaning. However some material may cause a buildup in the valve chamber, in this case periodic and
thorough cleaning will be required.
CAUTION: Make sure the fluid pressure is released before disassemble the valve.
