With over two decades of continuous presence in the valve industry, VOG Omid Golestan is recognized as a leading manufacturer of cast-iron and steel valves for water, wastewater, oil & gas, and agriculture. An expert engineering team, in-house foundry, and modern CNC machining lines allow the company to manage the full cycle—from design to packaging—under one roof. The result: shorter lead times and tighter quality control.
Production Infrastructure & Technology
- Precision casting of gray and ductile iron using energy-efficient induction furnaces.
- Metallurgy lab with hydrostatic and pneumatic testing up to 64 bar.
- Epoxy and polyurethane powder-coating lines with controlled film thickness for corrosion resistance.
- Integrated QMS aligned with ISO 9001, ISO 14001, ISO 45001, plus part-traceability software through installation.
Product Portfolio & Applications
VOG Omid Golestan covers a wide range of operating needs—from water treatment plants to petrochemical units.

- Participation in water-loss reduction and energy-recovery programs; recyclable alloys and energy-efficient production.
Selection Guidelines
Before specifying, document medium properties, operating temperature, nominal pressure, and installation constraints. Urban projects often prefer wafer bodies for tight spaces, while refineries select full-flanged bodies for higher rigidity. Use the company’s hydraulic simulation service to align pressure drop with network design requirements.
