Armaseal 322 is a packing obtained with graphite rings with section "cup and cone"
and is designed to fulfill the new norm on the "fugitive leak emission".
It is specially used to operate on gate, disc, ball, butterfly valve stems
etc. of any dimension and for any kind of application, at different working pressures,
for high and low temperatures (-196°C and max 650°C in oxidant room). This new packing,
taking advantage of the different ring geometry, allows to operate in the opening and
closing fase with low twisting moments, lower than 500 Nm, normally required by the
specifications. This characteristic permits Armaseal 322 to obtain the
API Standard 622 conformity.
