These rupture discs are a compression-loaded disc or reverse-acting
disc, scored around the circumference. This disc has been designed to
meet the high quality standards required by 3-A SSI, whose aim is to
ensure public health through hygiene equipment. The FSKRDS model is
particularly suitable for the Pharmaceutical, Food, and Biotechnology
industries and represents the state-of-the-art for these sectors. This
disc is entirely made of AISI 316L stainless steel (or other alloys upon
request of the client). It’s smooth surface makes it particularly
suitable for C.I.P. and S.I.P. treatments to maintain aseptic
conditions. PTFE gaskets, which are certified in compliance with FDA and
USP class VI, 3-A, and Eu 10/2011 regulations, facilitate the
installation in Clamp fittings (sanitary, Tri-Clamp, Tank Connection).
The operating pressure modifies the camber of the convex disc only when
reverse pressure is reached. Upon reversal, the disc opens completely in
a few milliseconds along the score line, thus preventing fragmentation
from forming. The FSKRDS disc, with its innovative design, can be used
with liquids only and can resist both vacuum and high pressure.
