Chemical resistance chart helps designers select the right valve
Published: 6 January 2014 - Rachael Morling
Bürkert has released a comprehensive chemical resistance chart which matches products, materials and conditions with chemical type and reactivity to help designers and maintenance engineers select the most suitable valve every time.
Designed to simplify the selection of suitable materials when using Bürkert products for aggressive fluids, the guide aims to provide useful information on the best choice of housing and gasket material. If the production process involves liquid food products, the plastics and elastomers used should conform to the local food and hygiene regulations for example.
The guide, which is available here in pdf format from the Bürkert website, provides an overview of the basic materials used in valve construction and then relates these materials to basic chemicals, commercial products and liquid food products. Each valve material is rated for resistance to chemical attack by each individual chemical as suitable, limited suitability or unsuitable.
Customers are advised to carry out testing of samples in actual operating conditions and use the chart as a guide rather than an absolute specification tool. Further assistance with specific applications can also be found by contacting the Bürkert technical support team.
