【Applied Range

EPDM Butterfly Valve disc materials are optional, such as nylon coated discs, galvanized coated discs, CF8 (SS304) discs, CF8M (SS316) discs, and the like. The choice of valve disc is determined by the customer's medium.

For pipes, usually, if it is not corrosive, galvanized sheets are fine. For corrosive services we can choose between 304 or 316 discs or nylon coated discs.

EPDM Butterfly Valve's seal seat includes NBR rubber, EPDM rubber and fluoro rubber. The temperature resistance of NBR and EPDM is about 80 ° C (maximum). The temperature resistance of Viton rubber is about 150 degrees Celsius. NBR rubber is also resistant to oil, EPDM rubber is resistant to aging, and Viton rubber is resistant to weak corrosion.
