V
virgin PTFE
Virgin polytetrafluoroethylene 100% PTFE
Our standard seat material. Ideal for most
sanitary services. Specified for applications
requiring a low co-efficient of friction.
Food Grade Material
G
RTFE
15%
Glass reinforced
tetrafluoroethylene
15%
Glass filled + 85% PTFE
Slightly higher temperature and pressure rating
than PTFE. Specified for applications requiring
higher cycle life than PTFE.
Food Grade Material
C
25%
carbon PTFE 25% Carbon reinforced
tetrafluoroethylene
25%
Carbon +75% PTFE
Specified for higher temperature pressure
applications. Ideal for steam and thermal fluid
applications. Higher cycle life than RTFE.
S
stainless steel PTFE 50% Stainless steel filled
tetrafluoroethylene
50%
Stainless steel + 50% PTFE
Specified for higher temperature pressure
applications in a sanitary process.
Food Grade Material
U
UHMW
Ultra-high molecular weight
polyethylene
Specified for its low modulus of abrasion and
minimal property degradation when exposed
to moderate levels of radiation. Ideal for
applications where fluorocarbons are not
acceptable.
