The ENVIRO-SEAL PTFE packing system is suitable for
100 ppm environmental applications on services up to
51.7 barg (750 psig) and process temperatures
ranging from -46 to 232

C (-50 to 450
_
F).
For non-environmental applications, this packing
system offers excellent performance at the same
temperature range up to the maximum valve working

Temperature limits apply to packing arrangements
only. Complete valve assembly temperature limits may
differ. Refer to appropriate pressure/ temperature
ratings.
