Dome seals
January 1st 2009 Replacement dome seals for use in
the food and pharmaceutical sectors
are available from James Walker
Keaflex.Made from Elast-OPure(
R), an ethylene-propylene
(EPDM) synthetic rubber
compounded in-house by James
Walker, seals come in a range of sizes.
The design and reliability of dome
valves have led to their adoption in a
range of industries for controlling
the flow of bulk materials such as
powders, pastes and granules. They
are compressed air operated, and use
an inflatable sealing mechanism
which provides a pressure tight seal
when in the closed position.
Elast-O-Pure is rated to USP 30
Class VI classification for
pharmaceutical use. More articles from James Walker Keaflex: |
