The Oseco Type FLCO provides low pressure relief from 1 PSIG to 50 PSIG and is available in sizes 2" through 36" diameters. The FLCO fits between standard ANSI flanges. It is not torque sensitive and has the same burst pressure in either direction. The FLCO is suggested for applications in which the normal operating pressure does not exceed 50% of the rated burst pressure.

The FLCO is supplied from standard rupture disk materials and is encapsulated with Fluoropolymer liners. Corrosion-resistant Fluoropolymer is in contact with all process media. The FLCO is provided with non-asbestos gaskets and can be supplied with other specific gasket materials; consult factory with your specific requirements.
