Sealing Materials for Valve Bodies and Cones

Working Temperature Typical Application Area

MVQ
Silicone

resistant in waters up to
100 °C
suitable for temporary steam sterilisation up to 130 °C

high thermal capacity
good resistance to cold
for foodstuffs
dielectric properties
good resistance to alcohols
EPDM

constant operation temperature from 40 °C through to 140 °C
suitable for temporary steam sterilisation up to 130 °C (up to max. 180 °C)

good resistance to swelling with:
diluted inorganic and organic acids, bases,
polar organic media, media with an oxidising effect, brines and ketones in hot water and steam up to 130 °C
FPM (nach DIN-ISO)
FKM (nach Norm ASTM)
Viton®

constant operation temperature from -20 °C through to 200 °C
suitable for temporary steam sterilisation up to 140 °C
(from min. -35°C and max. 230°C)

good resistance to swelling with:
mineral oils, vegetable and animal oils
fats (also special additives)
petrols
NBR
Perbunan®

constant operation temperature from -25 °C through to 110 °C
suitable for temporary steam sterilisation up to 130 °C
(up to min. -60°C)

good resistance to swelling with:
aliphatic hydrocarbons (such as propane, butane, petrol, mineral oils)
fats on mineral oil basis
PTFE
Teflon®
physiologically harmless up to 200 °C
suitable for use from
-200 °C through to 260 °C

smooth and repellent surface, thus no adhesion of residues, better chemical resistance than with all elastomers, hardly combustible

CR,NR -30 °C through to 90 °C
for special applications
flame resistant, resistant to welding, weather resistant,
resistant to deterioration, resistant to saline waters, frequent use in cooling agents
FFKM/ FFPM
Karlrez®, ISOLAST®

-20 °C through to 275 °C
with special compounds temperatures from -30 °C through to 325 °C can be reached

very good thermal or chemical resistance
(to very aggressive media)
FEPM -30 °C through to 200 °C high resistance especially to amine-containing additives and corrosion inhibitors
VA
Graphit
-200 °C through to 500°C use at high temperatures
for corrosive media
not sensitive to scratches,
very high resistance to chemicals
EU
Eladur™
-20 °C through to 80°C mostly used with gases, e.g. CO2, nitrogen, air, also used with water
high tear resistance, good thermal properties
