Duplex Steel Valves Manufacturer in India

Ridhiman Alloys is Duplex Steel Valves Manufacturer which produces precision engineered valves manufactured with high performance material like Duplex steel stainless steel UNS S31803 and S32205. These valves have a reputation of being strongly resistant to corrosive environments, being of a high mechanical strength, and being easily welded. They find much application in heavy industrial applications such as chemicals, offshore oil rigs, marine, and pulp & paper plants. These valves meet international standards, including ASTM A995, BS EN 12266, and IS 13095 thereby making the valves reliable when subjected to extreme pressure and temperature. 

Our B2B site has a well-tested portfolio of Duplex steel valves that will serve the technical and logistical requirements of your project. Our valves are all of guaranteed durability and straightforward installation and can also be customized; this makes them very suitable for large orders and in case of longer-term usage. Our quality and lean supply chain guarantee you the best-in-class industrial valve solution, no matter what type of hostile environment or critical flow-control system that you require it to source.


Type of Sub-products

  • Duplex Steel Ball Valve
    Duplex Steel Ball Valve

    Duplex Steel Ball Valve

    They are quarter turn valves operated by a rotating ball to operate the flow. They are manufactured out of Duplex SS and are wear and corrosion resistant even under aggressive media. Very suitable in chemical industries, marine pipelines, and water treatment systems where they are needed to have a good shut off.

  • Duplex Steel Gate Valve

    Duplex Steel Gate Valve

    Duplex Gate Valves have full flow, linear motion configurations, having zero leakage sealing. They are stronger in structure that can deal with systems subjected to high temperature and high pressure, which are normally witnessed in oil refineries and power plants.


Frequently Asked Questions

What are Duplex Steel Valves made of?

Duplex Steel Valves are made from a mix of austenitic and ferritic stainless steels, most commonly UNS S31803 and S32205. This dual-phase structure provides high strength, superior resistance to pitting and stress corrosion, and excellent performance in aggressive environments.

What industries use Duplex Steel Valves?

These valves are widely used in offshore oil & gas, petrochemical plants, chemical processing units, desalination systems, and pulp & paper industries. Their resistance to chloride-induced corrosion makes them ideal for marine and coastal applications.

How do Duplex Valves perform in high-pressure systems?

Duplex Steel Valves can operate under high pressure and fluctuating thermal conditions. This makes them suitable for high-load and cyclic applications in refineries and offshore facilities.
