HO/HOV SERIES
DESCRIPTION
Fike’s HO Rupture Disc is a composite disc consisting of two components,
the seal member and a slotted top. In this conguration the slotted top
section contains the seal and the seal transmits the pressure load to the top
section. The slotted top section controls the burst pressure of the disc and
allows the use of uoropolymer as a seal member. In addition to the
typical seal materials available, tantalum, titanium or other precious metals
may be used when dealing with corrosive media. The HOV Rupture Disc
(high operating and vacuum) is constructed the same as the HO Disc with
the addition of a vacuum support under the seal member.
The HO/HOV is commonly manufactured with a 316 stainless steel top
section and vacuum support with an FEP uoropolymer seal member for
temperatures up to 400°F (204°C). Alternate seal materials are available, see
table on the following page for burst pressure ranges per size and seal material.
Alternate top section and vacuum support materials are available as well, such
as Nickel, Monel, Hastelloy, Inconel and Tantalum.
