Ceramic lined valves for inorganic and organic chemicals
As we know, in many industries today the use of chemicals to serve the daily production process, the use of chemicals can be in the form of solids or liquids, it is contained in the basin and piping leading to the site of use. To ensure safety and avoid risks, storage tanks and pipelines must also be made of materials resistant to chemical environments.
Chemical resistant valves are installed on pipelines with the opening and closing effect, controlling the flow of chemicals to ensure the proportion of chemicals used as prescribed. In the past, people often made valves with chemical resistant materials, but after a while, the valves were also damaged, so the process of using chemical resistant plastic lining valves was born. It greatly improves valve life and maintenance time. But the disadvantage of Teflon, PTFE or PFA and PO plastic lining valves is that it is resistant to certain chemicals, so it is difficult in terms of solvent diversity. In recent years, ceramic valve lining technology has been born, with Alumina ceramic from 95%, 99% and 99.5%, bringing great requirements for chemical resistance.
With ceramic valve Alumina 99.5% or more resistant to most inorganic and organic chemicals, corrosive acids with high concentrations or alkaline chemicals: HCL, H2SO4, H3PO4, HNO3, HF, NaOH …
Why use V2P ceramic valve for chemical environment?
1- Inert with chemicals: With Alumina ceramic valve 99.5% or more or with Silicon Carbide almost inert with all inorganic or organic chemicals. It does not interact as well as is physically and chemically stable, resisting most acids and alkalis.
2- Abrasion: Ceramic lining valve (ceramic) has 750% harder than stainless steel, 43% harder than zirconia, 140% harder than normal porcelain.
3- Durable: Even when soaked in chemicals for a long time, the ceramic lining valve is not affected, it gives long-term use.
4- Warranty up to 12 months.
Different ceramic lining materials for different applications:
1- Alumina (Al2O3) is the most economical ceramic lining material but has high corrosion and abrasion properties
2- Zirconium (ZrO2) for high durability but only withstand temperatures up to 320 degrees Celsius
3- Silicon Nitride is used for high temperature resistant applications, maximum temperature is 950 degrees Celsius
4- Silicon Carbide (SiC) For highest hardness in the group of ceramic materials but very low breaking strength, so it is easy to break. It is inert with most chemicals, especially HF acid.
