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.
a) . The sealing accessory material is matched with stainless steel and nitrile oil resistant rubber, and has a long service life.
b) . The rubber sealing ring can be located on the valve body or on the butterfly board, and can be applied to different media for users to choose.
c) . The overall baking varnish can effectively prevent rust and can be used for different media as long as the sealing seat sealing material is replaced.
d) . The valve has a two-way sealing function, which is not controlled by the flow direction of the medium during installation, and is not affected by the spatial position.
e) . EPDM Seated Butterfly Valve has light weight, reliable performance, simple matching and large circulation capacity, especially suitable for medium is clean liquid and gas.
