Super Duplex 5A valves, Duplex 4A valves, and 254 SMO valves in desalination equipment

Zipson offer several kinds of Duplex material valves. Different materials are suitable for different working condition. Chose the proper valves in desalination equipment is not only to save the cost but also prolong the working life time.305F, 3-pc 254 SMO flanged ball valve

254 SMO valves (CK3MCuN):

Features: 254SMO is a high-nickel, high-chromium, high-molybdenum austenitic stainless steel known for its outstanding corrosion resistance, particularly in environments containing salt, sulfuric acid, or alkaline conditions.
Application: In seawater desalination equipment, 254S MO valves is commonly employed in areas with high chloride content, such as in regions dealing with concentrated brine during the desalination process.

Super Duplex 5A valves (CE3MN):

Features: Super Duplex 5A is a high-strength, highly corrosion-resistant duplex stainless steel containing elements such as chromium, nickel, and cobalt. It possesses excellent corrosion resistance and resistance to stress corrosion cracking.201D, 2-pc Duplex ball valve
Application: In seawater desalination equipment, 5A valves is typically used in high-pressure, high-temperature, and high-chloride environments, such as in high-pressure pumps and pipelines in reverse osmosis and pressure filtration equipment.

Duplex 4A valves (CD3MN):

Features: Duplex 4A is a duplex stainless steel containing elements like cobalt, chromium, and nickel. It combines features of both austenitic and ferritic stainless steels, offering higher strength and corrosion resistance, particularly in chloride-containing environments.
Application: In seawater desalination equipment, 4A valves can be utilized in lower pressure and milder corrosion environments, such as in some of the more moderate filtration and pretreatment stages of the process.
The choice of these materials depends on specific application scenarios, environmental conditions, and operational parameters of the equipment. To ensure optimal performance, valves in desalination equipmentit is recommended to consult with a materials engineer or experts with relevant expertise during the design and material selection process.

Duplex components:

If Super Duplex, Duplex or 254 SMO components are needed for your specific application to prevent from corrosion from salt dust or sea water, Zipson foundry are able to offer such parts for the customers.
