Qnity brings Kalrez sealing solutions to valves
Qnity Electronics has introduced Kalrez® sealing solutions for industrial valves, applying materials expertise from semiconductor manufacturing to sealing duties in various sectors including semiconductor, chemical, energy, and others. This move marks a significant advancement in valve technology and reliability.
Kalrez is a perfluoroelastomer (FFKM) that offers exceptional resistance to aggressive chemicals and high temperatures. It's ideal for valves used in demanding environments where standard elastomers fail. The introduction of Kalrez® by Qnity brings enhanced durability and chemical resistance, making it suitable for applications requiring extreme conditions.
What are the key benefits of using Kalrez seals?
Kalrez seals provide unparalleled performance in high-temperature and chemically aggressive environments. They don't degrade like traditional elastomers do under harsh conditions. For instance, Kalrez can withstand temperatures up to 316°C (600°F), far beyond what conventional rubber materials can handle.
The material's chemical resistance is also remarkable; it resists hundreds of chemicals that would destroy other seals. This makes it perfect for semiconductor manufacturing and chemical processing where purity and reliability are important.
How does this impact UK procurement managers?
For UK procurement managers, the introduction of Kalrez® by Qnity means access to a higher-performing seal solution. It reduces maintenance costs and downtime associated with frequent replacements due to material degradation. For example, in semiconductor manufacturing plants, where contamination can cost millions, using Kalrez seals could save up to £500,000 per year in lost production.
What are the typical applications for these valves?
Kalrez®-sealed valves find their place in sectors such as pharmaceuticals, petrochemicals, and food processing. They're also critical in semiconductor manufacturing, ensuring clean rooms remain free of contaminants. These valves can operate continuously without degradation, making them ideal for long-term use in demanding environments.
How does this affect UK component suppliers?
UK component suppliers now have the opportunity to offer a premium product that enhances their competitive edge. By stocking Kalrez®-sealed valves, suppliers cater to industries requiring strong sealing solutions. This move can attract larger clients and secure long-term contracts in high-stakes sectors.
What standards does this align with?
Kalrez seals comply with international standards such as ISO 13719 for valve testing methods and BS EN 12266-1 for flanged valves. At Qnity brings Kalrez sealing solutions to valves, these standards ensure that the sealing solutions meet rigorous quality requirements, providing peace of mind to engineers and procurement managers.
How can MLC users benefit from this news?
MLC users seeking high-performance components for their projects now have a reliable supplier in Qnity Electronics. The site lists various valve categories such as pneumatic valves. Hydraulic valves, and control valves, all of which can be enhanced with Kalrez seals. This addition ensures that UK engineers have access to modern sealing technology directly through the MLC platform.
What's next for Qnity?
Qnity plans to expand its range of Kalrez®-sealed products, offering even more options for industries facing challenging conditions. They aim to collaborate with leading engineering firms in the UK and globally to drive innovation and improve operational efficiency across various sectors.
In summary, Qnity's introduction of Kalrez sealing solutions is a game-changer for valve technology. Qnity brings Kalrez sealing solutions to valves offers superior performance and reliability, benefiting procurement managers, engineers, and component suppliers alike. With MLC as a resource, UK users can easily find and integrate these advanced components into their projects.
