As a respected global supplier of sealing technology, James Walker offers a comprehensive range of sealing technology and proprietary components covering virtually every valve application.

James Walker has been in the business of fluid sealing and control since the company’s founding over 130 years ago. From our earliest products and throughout our history the company has developed sealing solutions and components in parallel with advances in valve technology. As a result we have amassed specialised knowledge of applications across a very broad range of industries.

From chemical processing and nuclear energy to subsea valve applications in oil and gas, our experience drives innovations in materials and sealing technology that help facilitate production and performance advances.

We have an extensive range of world-class products and specialised materials including the latest generation of rapid gas decompression (RGD) resistant elastomers, the world-leading Supagraf® range of graphite-based fugitive emission packing plus innovative Devlon® V-API thermoplastic valve seat technology.

Many of our products meet or exceed the required international standards in reducing volatile organic compound (VOC) fugitive emissions from valves, pipelines, processing plant and pressure vessels as well as demonstrating Best Available Technique (BAT) under the European Union’s Integrated Pollution Prevention and Control (IPPC) directive.
