【Product Structures

*Rubber Lined Butterfly Valve generally has two structures:

a). Fully lined butterfly valve. Both the disc and the valve body are rubber-lined.

b). Half-lined butterfly valve. Usually the body seat is rubber lining and the disc is not.

Sometimes customers ask for a lining, and the body seat is not required.General lining rubber materials include EPDM, NBR, Viton, PO, NR, etc.Due to lining material limitations, this Rubber Lined Butterfly Valve is used at temperatures not higher than 150 degrees Celsius.
