Dome Seal

Kea-Flex manufactures dome seals for use in the food and pharmaceutical sectors. Made from Elast-O-Pure®, an ethylene-propylene (EPDM) synthetic rubber compounded in-house by James Walker, the seals are available in a wide range of sizes.

The simple design and high reliability of dome valves have led to their adoption in a wide range of industries for controlling the flow of bulk materials such as powders, pastes and granules. The valves are compressed air operated, and use an inflatable sealing mechanism which provides a pressure tight seal against the dome when in the closed position. 

Elast-O-Pure is specifically formulated for use in pharmaceutical and bioprocessing environments and is rated to USP 30 Class VI classification for pharmaceutical use. 

Kea-Flex produces the valves in standard diameters from 50 mm to 400 mm, using a single cavity tool, and can make other sizes on request.
