Maintenance
Veriflo valves are packless and do not require packing adjustment. Do not loosen
or remove the clamp nut. A valve should be checked periodically for proper and
safe operation. A valve should also be checked after cylinder changes or system
maintenance. The user is solely responsible for determining the frequency of
maintenance based on the application, that the recommended checks can be safely
performed, and that the recommended checks are adequate to ensure proper and safe
operation of the user’s system. A valve that does not comply with the recommended
checks or malfunctions in any manner must be immediately removed from the service.
Do not attempt to repair the valve.
•
Check for valve seat leak. With the valve closed, there should be no leak across
the valve seat. Leak test methods should be appropriate for the system leak
integrity requirements.
•
Check for leaks to atmosphere. With the valve open, there should be no leaks
to atmosphere. Leak test methods should be appropriate for the system leak
integrity requirements.
Removing a valve from service:
Follow your system safety and maintenance
procedures when removing a valve from service. Before removing a valve, the user
must:
•
Isolate the valve from all pressure sources upstream and downstream of the
valve by closing the appropriate valves.
•
Lockout valves and other system equipment needed to isolate pressure sources.
•
Properly purge hazardous gases from the valve.
•
Vent all pressure in the valve. The valve should be open to ensure pressure is not
trapped in the valve.
