Operating from a world-class, 3,000 sqm facility, FEMA executes large-scale, complex projects without limitation on valve weight or pressure ratings. Certified to rigorous international standards (including ISO 9001:2015, ATEX, and PED Module B+D), their specialty valves serve critical sectors like oil & gas, chemicals, aerospace, and cryogenics.
Its aluminium body and PTFE sealing are specified for compatibility with liquid nitrogen, liquid oxygen, and liquid argon at temperatures down to -203°C.The piston design ensures a positive, repeatable shutoff under reverse flow conditions at pressure ratings up to 422 bar - an exceptional figure for a cryogenic check valve. Available in ½" to 3" flanged configurations, it is deployed in cryogenic fill lines, vessel outlet connections, and pump discharge circuits.
