WV Packings
While similar to Vee Packings, the WV style provides sealing properties
that are largely independent of stack packing pressure. The WV is
designed so that it will provide a multiple lip seal in a fixed gland depth
that is usually shorter than the gland depth required for a standard Vee
packing. Because of the design of the WV packing, the lips of each ring
are free to flex when in a nested stack so each lip automatically reacts
to fluid or air pressure, providing a better seal in a given packing space.
There is no compression adjustment required during the seal life.
Since the WV packing is a multiple lip seal, it is recommended over a sin-
gle lip seal for applications where side loading is a factor. The multiple lip
also provides extra stability. If one seal fails, there will be another seal to
serve as back-up.
There is an interference built into both the I.D. lips and the O.D. lips so that
there will be sealing capabilities at low pressure.
American Packing presently stocks Center Ring and Flat Back WV pack-
ings in homogenous Buna 90 Durometer and fabric reinforced Buna.
