Severe Service Control Valves

 As a global supplier, Severn Glocon Group plc is setting the pace in the control valve marketplace. By reacting to current market trends with a combination of technologically leading products and services as well as a worldwide sourcing capability, the Group ensures quality and price advantage.

Severn Glocon Group is renowned for its 40-plus years of supplying Choke and Severe Service Control Valves. Its designs are suitable for oil & gas applications, low temperature LNG and air separation applications as well as high temperature power generation demands. However, 49 years’ experience means nothing unless you put it to use with modern manufacturing practice combined with updated engineering standards and materials. Across Severn Glocon Group there has been investment to support the current environment and ensure the business occupies the top decile of international valve suppliers.
