Colson Valves supplies instrumentation and double block & bleed valves into some of the most demanding operating environments in the world. Across oil & gas, energy and power generation, defence, chemical and petrochemical, and the emerging renewables and energy transition sector, the common thread is the same: safety-critical applications where valve failure is not an option and documentation has to withstand scrutiny. Every sector we work in brings its own operating conditions, standards and regulatory requirements. Our engineering team specifies accordingly, rather than applying a generic approach to a specialist application.
