Alloy 20 Check Valve



Carpenter 20 Poppet check valve manufacturer in India

Various alloys are used in manufacturing check valves. One such alloy used to manufacture such valves is the  Alloy 20 Check Valve. They contain nickel chromium and molybdenum and are specifically designed to be used in applications that contain sulfuric acid. Moreover, they are also said to resist chloride corrosion cracking and pitting.

alloy 20 check valve manufacturers in India recommend the use of these valves in flue gas desulfurization, food processing, and certain pharma operations. They can be hot formed or cold worked. Moreover, they are also used in heat exchangers, condensers, pulp and paper industry, power generation, and so on.

 UNS N08020 Spring Check Valve is also used in off-shore drilling companies, petrochemical processing, pharmaceutical, seawater, and chemical equipment. These valves can resist acid strikes namely sulfuric acid. Moreover, a minute quantity of niobium can be added to the alloy this enhances the resistance of the alloy to sensitization. 

Moreover, the addition of niobium to WERKSTOFF NR. 2.4660 Hydraulic Check Valve also makes it resistant to intergranular corrosion. The alloy used in the production of these valves is said to possess good fabricability. The size of these valves ranges from ½ inch to 48 inches. 

Carpenter 20 inline Check Valve is widely used in pickling racks, tanks, food and dying industries, and other environments. These valves have a working temperature ranging from -29 degrees C to +180 degrees C and a size range of ½ inch to 4 inches. The melting point of carpenter 20 valves goes up to 1443 degrees C with a density of 8.1 g/cm3.
