Code Designation Material Applications
V Virgin PTFE Virgin
polytetrafuoroethylene
100% PTFE- Our standard seat material. Ideal for most sanitary
services. Specifed for applications requiring a low co-effcient of
friction.
3A and FDA approved.
G RTFE 15% glass reinforced
tetrafuoroethylene
15% glass flled + 85% PTFE - Slightly higher temperature and
pressure rating than PTFE. Specifed for applications requiring
higher cycle life than PTFE.
3A and FDA approved.
C 25% Carbon PTFE 25% carbon reinforced
tetrafuoroethylene
25% carbon +75% PTFE - Specifed for higher temperature
pressure applications. Ideal for steam and thermal fuid
applications. Higher cycle life than RTFE.
S Stainless Steel PTFE 50% stainless steel flled
tetrafuoroethylene
50% stainless steel + 50% PTFE - Specifed for higher temperature
pressure applications in a sanitary process.
3A and FDA approved.
U UHMW Ultra-high molecular weight
polyethylene
Specifed for its low modulus of abrasion and minimal property
degradation when exposed to moderate levels of radiation. Ideal for
applications where fuorocarbons are not acceptable.
3A and FDA approved.
