Since the 1960s: Farab, a pioneer in cast-iron valves
Farab has been synonymous with innovation since Iran’s first cast-iron valve casting line started in the 1960s. The company’s formal market entry in 1986 with mass-produced cast-iron butterfly valves marked a turning point. Continuous R&D investment has added CNC machining lines, a 40-bar hydrostatic test lab, and component life-cycle simulation. Today, Farab is a trusted supplier to national projects in oil & gas, combined-cycle power plants, water treatment, and urban water networks.
Quality philosophy at Farab
- Integrated Management System (IMS): ISO 9001:2015, ISO 14001:2018, ISO 45001:2018
- Digital production monitoring via IIoT sensors with full supply-chain traceability
- Destructive & non-destructive tests (UT, MT, PT) per ASME B31.1
- Ongoing workforce training through the Iranian Foundry Society workshops
These practices have reduced product returns to under 0.8% and secured Farab’s inclusion on category-A Approved Vendor Lists (AVL) of leading EPC contractors.
Product range & applications
To cover diverse process needs, Farab manufactures five core valve families:
- Butterfly valves — Class 6 to 300, wafer and lug types; for clean or corrosive media, −20 to +200 °C.
- Gate valves — Metal, resilient, or graphite wedge; ideal for raw-water distribution and pump stations.
- Globe valves — S-type design with hardened stainless disc; precise flow and pressure control in boilers.
- Check valves — Swing and disk types; mitigate water hammer in long transmission lines.
- Strainers — 304 SS screens with replaceable meshes; extend pump and rotating-equipment life.
