Valvesonly is a Super duplex gate valve manufacturer in the USA. The super duplex gate valve is made up of a hand wheel, a threaded stem that extends from the handwheel to the gate within the body, and the gate and body. Any material other than the body may be used to make the doors. The motion is regulated by the gate, which blocks and opens the passage. The corrosion resistance of super duplex valves is excellent. They have applications in food manufacturing, pharmaceuticals, chemicals, and other industries.

Characteristics of Super Duplex Gate Valves:

• It has High resistance.
• It has High Strength.
• A mixture of properties given by austenitic and ferritic structures.
• Good weldability and workability.
• It has excellent resistance to chloride.
• It has good corrosion resistance.
• It can be suggested for applications up to 600° F.
• Very low rate of thermal expansion.

Where it is used:

Shipbuilding, chemical industry, seawater desalination, oil and gas industry, petrochemical industry, and other industries all use Super Duplex valves. Because of their high corrosion resistance and strength, these valves are used in a variety of industries. Because of the various processes, super duplex steels have different stage names.

References codes of super duplex valves:

A variety of reference codes and normalization codes can be used to recognize super duplex valves. By Using American ASTM standards, if you are looking for a forged super duplex valve, you will ask for an A182 F53 or F55 valve; however, if you were looking cast super duplex valve then you would be looking for an A955 Gr. 5A valve or A955 Gr. 6A valve or an A351 CD3MWCuN valve, previously named as an A890 Gr. 5A or 6A valve. Super duplex is identified as 1.4501 and 1.4410 as per German DIN norms.
