Fajar Nickel Alloys, Jakarta, Indonesia, is a leading producer and supplier of Super Duplex Ball Valves. Designed for high strength, durability, and corrosion resistance, our valves are most suitable for harsh industrial use. Robust enough to tolerate high pressure, severe chemicals, and heavy temperatures, they provide long-term reliability and safe operation. Predominantly applied within chemical processing, offshore gas and oil, and power generation, these valves conform to rigorous international quality levels. Fajar Nickel Alloys provides precision-fabricated ball valves that outperform expectations, making us the go-to partner for customers who demand strong and efficient flow control solutions.
Super Duplex Ball Valves are constructed from Super Duplex Stainless Steel (usually UNS S32750 or S32760), having a balanced austenitic-ferritic microstructure. They provide high tensile strength (generally in excess of 750 MPa) and better yield strength. These valves offer fine resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-strewn and acidic environments. Their heavy-duty design confirms leak-tight performance under high pressure and temperature variations. With superior mechanical strength, toughness, and weldability, Super Duplex Ball Valves assure long-term reliability in the toughest industrial applications.

Super Duplex Ball Valves find wide application in industries where high mechanical strength and resistance to corrosion are needed. In the oil and gas industry, they are crucial for subsea equipment, offshore platforms, and pipeline systems for high-pressure fluids and corrosive chemicals. In the chemical industry, they control acidic and corrosive media efficiently and safely. The valves are also utilized in coastal environments, power plants, and desalination plants, where they face seawater exposure and high temperatures. Due to their strong build and leak-free operation, they are the first choice for critical operations under severe environments.
