This maintenance manual is provided because you have Farris Engineering
2600 Series pressure relief valves protecting equipment and personnel in
your plant. We trust that you will find this manual useful, as it is intended
to clearly present all the essential information you will need in order to
keep your Farris valves in perfect operating condition.
Any maintenance and repair work or testing performed on Farris pressure
relief valves should be done in strict accordance with the requirements of
all applicable Codes and Standards. Persons performing the work should
maintain proper authorization through applicable governing authorities.
To ensure reliable and safe operation, installation, testing, maintenance,
adjustment, and repair of Farris valves, these activities shall only be
performed by qualified personnel having the required skills and training.
No repair, assembly, adjustment or testing performed by individuals other
than Farris-authorized representatives shall be covered by the warranty
extended by Farris to its customers. All applicable regulations, directives,
codes and standards shall be adhered to when performing these activities.
Failure to follow proper test procedures or failure to use proper test
equipment will lead to incorrect test results, damage to the valve and will
invalidate the warranty.
Farris Engineering provides programs which coordinate classroom and
hands-on training. It is recommended that individuals performing pressure
relief valve maintenance receive training specific to those valve series they
expect to repair and set. Only this type of training will ensure the proper
application of these instructions. The National Board of Boiler and Pressure
Vessel Inspectors conducts training programs on valve repair in conjunction
with their VR program. This is a broad-based program and is recommended
to supplement training received from specific manufacturers.
These instructions do not cover all details or variations in equipment,
nor do they provide for every possible contingency to be met in regards
to installation, operation or maintenance. Should further information be
desired or should particular problems arise which are not covered
sufficiently for the purchaser’s purposes, please contact Farris Engineering.
