All our butterfly valves use EPDM seals as standard. EPDM is the most widely used material in the food and beverage industry.    Static seal temperatures Gasket Properties EPDM VITON Heat resistant Excellent (275°F) Excellent (400°F) Cold resistant Good-Excellent (-20°F) Good-Excellent (-30°F) Steam Good Excellent Abrasion-resistant Good-Excellent  Good Alkali Good Poor-Good Acid resistance Good-Excellent  Good Vegetable oil Good Excellent Petroleum oil Poor Excellent Oxonia Good-Excellent  Excellent Ozone Good-Excellent  Excellent   Note: The surfaces in contact with a seal determine what type to use. The surface can either be static or dynamic, in motion or without movement. Static seals are usually used when there is no relative motion between mating surfaces. Dynamic seals are the opposite. They are used when there is motion between surfaces. This can be either reciprocating or oscillating motions. Dynamic application in combination with high temperatures also affect the properties of elastomers. Dynamic seal: A dynamic seal is exposed to movement.Examples: Butterfly valve gaskets Max.
