Since 1982, AeroFlex has manufactured high-durability knife gates, flap valves, expansion joints, and bellows designed to withstand the harshest African industrial, mining, and power generation environments.

Design Target in High-Pressure
In industrial environments, equipment failure is not an option. A single blown expansion joint or jammed gate valve can halt entire production lines, causing millions of Rands in downtime. At AeroFlex, our engineering team has over four decades of hands-on expertise in developing specialized flow equipment for thermal power plants, heavy chemical operations, bulk handling, and mineral processing mills.
Operating out of our advanced manufacturing facility on the East Rand, Johannesburg, we employ certified fabrication, rigorous pressure-testing procedures, and robust materials specification (including hard-facings, stainless steels, and exotic alloys) to guarantee maximum lifecycle value.
"Our designs do not just meet compliance standards—they are purpose-built to outperform them in the rugged, abrasive realities of the South African heavy-industry sector."
Specifically engineered for abrasive slurries, heavy powders, and viscous mining discharge. Designed with self-cleaning gates to prevent clogging.
Robust check-valves designed for drainage, outfalls, and water treatment systems to prevent backflow in both square and round configurations.
Elastomeric, metallic, and fabric joints engineered to absorb thermal expansion, contraction, and mechanical vibrations in pipelines.
Precision-formed metallic multi-ply and fabric bellows to safeguard pipelines under extreme pressures, protecting sensitive industrial infrastructure.
Every single valve is rigorously pressure tested in accordance with international standards before it leaves our floor.
Full material data reports (MDR) and certificates provided for all alloy components and specialized liners.
Got an unusual piping layout? Our team develops tailor-made modifications to fit non-standard flange dimensions.
