There are Differences Between Packing Systems
n Have Fisher ENVIRO-SEAL packing systems been
tested to industry-recognized fugitive emissions
standards for control valves?
•
Yes, ENVIRO-SEAL packing systems have been
successfully tested to ANSI/FCI 91-1 to meet LDAR
valve leakage requirements, as well as international
standards, such as ISO 15848-1, across a broad range
of pressure and temperature conditions.
•
Contact your local Emerson sales office for more
information and/or copies of relevant certificates.
n What is the performance impact of using
non-OEM packing?
•
Potential for degradation of control valve dynamic
performance and shutoff due to high friction.
• 
Unknown sealing characteristics due to generic
designs. Non-OEM packing commonly seals well in
the shop upon initial installation but can degrade
quickly once thermally and mechanically cycled in
the field.
• 
ENVIRO-SEAL packing systems are designed and
tested for Fisher control valves to provide optimal
dynamic performance in addition to 100 ppmv
low-emissions service. You don’t need to sacrifice
control loop performance in order to meet emissions
requirements.
n What is the difference between API 622 and ANSI/
FCI 91-1 or ISO 15848-1?
• 
Control valve standards ANSI/FCI 91-1 and
ISO 15848-1 require OEM valve model-specific
testing of packing designs.
• 
API 622 does not require valve model-specific testing
and requires only 1,510 mechanical cycles. API 622 is
most applicable to on/off and isolation valves, which
experience relatively few cycles in service.
•
ANSI/FCI 91-1 and ISO 15848-1 control valve
requirements range from 20,000–100,000
mechanical cycles.

n Does Emerson offer extended warranty coverage
for Fisher ENVIRO-SEAL packing systems to meet
my Enhanced LDAR requirements?
• 
Yes, customers with consent decrees requiring
100 ppmv Low-Emission (Low-E) or Certified
Low-Leaking packing are offered an optional
five-year warranty for ENVIRO-SEAL packing systems.
