<span style="color: rgb(85, 85, 85); background-color: transparent; box-shadow: none;"><b>Alloy 20 Valves</b> are high-quality <i>industrial flow-control products made of Alloy 20, which is a highly corrosion-resistant nickel-iron-chromium alloy designed to operate well in acidic, chloride-containing, and highly corrosive chemical environments</i>. Alloy 20 is designed to have excellent sulfuric acid, nitric acid, chlorides and saltwater resistance, and is a tough substitute to traditional stainless steels, namely 304 and 316, particularly in chemical processing.</span>

</div><p><br></p><div>
</div><div>The difference between Alloy 20 Valves is that they are <i>highly pitting, crevice corrosion and stress corrosion cracking (SCC) tolerant</i>. The existence of nickel, chromium, molybdenum, and copper facilitates a well-balanced microstructure that makes the performance to be consistent with the constant exposure to the severe corrosive media. The valves find extensive application in industries where the continuous flow of fluids and the service life are important.
</div><div><br></div><div>Chemical processing, petrochemical, pharmaceutical, <i>pulp and paper, marine engineering, water treatment and food and beverages production industries are industries that highly depend on Alloy 20 Valve</i>. These are intended to control, isolate and manage the movement of fluids in pipes and in equipment like reactor vessels, heat exchangers, pump systems and storage tanks.
</div><div><br></div><div>Operationally, Alloy 20 Valves are stronger in terms of <i>mechanical performance, thermal stability and pressure endurance.</i> They are built to accommodate different types of valves including <u>Gate Valves, Globe Valves, Ball Valves, Butterfly Valves, Check Valves and Plug Valves</u>. These valves may also be fed with various end connections such as flanged, socket weld, butt weld, and threaded ends depending on system needs.
</div><div><br></div><div>The other interesting feature is that Alloy 20 is relatively cheap when compared to high nickel alloys, in addition to having a great corrosion strength. This contributes towards making Alloy 20 Valves a better option in long-term industrial use where there is a need to have good service, minimal maintenance, and high longevity even under extreme conditions.
</div><div><br></div><div>In conclusion, Alloy 20 Valves offer an incredible combination of chemical resistance, durability, mechanical strength and versatility of usage in the most critical fluid control in corrosive industrial environment.

</div><p>These valves are used in industrial fields, e.g. chemical processing, petrochemical refineries, acid plant units, desalination plants, offshore fields, power generation system, and pulp and paper manufacturing plant. Alloy 20 valves are a best seller in the <b>b2b marketplace</b> especially when installing new equipment or when upgrading a plant. The Alloy 20 valves are often sourced by companies looking at the related corrosion-resistant types of valve materials like <b><a href="https://pipex.ai/product/alloy-valves-manufacturer-in-india-supplying-astm-standard-high-integrity-valve-solutions-for-oil-gas-power-process-industries-1025.html">Alloy Valves</a>&nbsp;</b>and<b> <a href="https://pipex.ai/product/valves-manufacturer-in-india-delivering-astm-api-certified-valve-solutions-for-oil-gas-power-process-industries-1025.html">Valves</a></b> to be used in similar operating environments.</p></div>
