Super Duplex Valve

Super Duplex Valves – Corrosion-Resistant Flow Control

This category encompasses our complete valve portfolio manufactured from Super Duplex Stainless Steel (UNS S32750, S32760), austenitic-ferritic stainless steel offering twice the strength of 316 SST with superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Material selection critically impacts valve service life, maintenance requirements, and total cost of ownership in corrosive African environments including offshore platforms, chemical processing plants, desalination facilities, and mining operations handling aggressive slurries and process chemicals.

Our super duplex valves range includes ball, gate, globe, check, and butterfly configurations meeting ASTM, ASME, and NACE material specifications with full material traceability and PMI (Positive Material Identification) certification. Applications span from West African offshore oil & gas requiring H₂S/CO₂ resistance to North African desalination plants demanding chloride resistance—serving international projects where material performance determines operational success.
