C-seal Trim Description
C-seal trim is available for valves with port diameters
from 2.875 inches through 8 inches.
With C-seal trim, a balanced valve can achieve
high-temperature, Class V shutoff. Because the C-seal
plug seal is formed from metal (N07718 nickel alloy)
rather than an elastomer, a valve equipped with the
C-seal trim can be applied in processes with a fluid
temperature of up to 593_C (1100_F).
ENVIRO-SEAL and
HIGH-SEAL
Packing Systems
ENVIRO-SEAL and HIGH-SEAL packing systems offer
exceptional sealing capabilities. They easily install in
your existing valves or can be purchased with new
valves. These systems may help prevent the loss of
process fluid. The long operational life and reliability of
these systems also reduces your maintenance costs
and downtime.
For applications requiring compliance with
environmental protection regulations, the unique
Fisher ENVIRO-SEAL packing system (figure 6) and a
unique ENVIRO-SEAL bellows seal system
(figure7)areoffered.Theemissioncontrolpacking
system keeps emission concentrations below the EPA
100 ppm requirement.
For an excellent stem seal in applications that are not
environmentally-sensitive, the Fisher HIGH-SEAL
Graphite ULF packing system (figure 6) is offered. The
HIGH-SEAL packing system provides excellent sealing
at pressure/temperature ratings beyond ENVIRO-SEAL
limits. ENVIRO-SEAL systems may also be applied for
excellent stem sealing i n higher pressure/temperature
applications not requiring EPA compliance.
ENVIRO-SEAL packing systems, available with PTFE,
Graphite ULF, or Duplex packing, and the HIGH-SEAL
packing systems, Graphite ULF and graphite
composite, feature live-loading and unique
packing-ring arrangements for long-term, consistent
sealing performance.
