The OsecoElfab (F)CO disc is a composite, forward-acting domed disc that delivers an excellent pressure performance range. With sizes ranging from 11/16” to 42”, the disc is ideal for applications with uncommon size requirements.

The design features a metal slotted top section with a slit-slot cover, and either a fluoropolymer or metal seal. The seal isolates the metal top section from the process media and prevents leakage. The patented “tear drop” feature of the (F)CO reduces the possibility of fragmentation on burst.

The (F)CO is designed for operation in applications where normal system pressures do not exceed 80% of the stamped burst pressure. This will ensure excellent and long service life.
