Regularly scheduled inspections should
be performed to check for:
• Actuator-to-valve misalignment
• Damaged housing or mounting
hardware
• Worn, loose or shifted parts due to
shock, vibration, etc.
STORAGE
Store in a clean, dry environment and
protect from severe temperature
changes and vibration.
NOTE: After Installation it is the
customers responsibility to be certain
that all set screws, terminal screws,
housing bolts and mounting bolts
are tight, and limit switches,
potentiometers and position
transmitters are calibrated to the
individual settings required for their
specific application.
