Valves for Chemical & Petrochemical

Colson manufactures instrumentation and double block & bleed valves for chemical and petrochemical applications, where process media, pressure and temperature conditions place particular demands on material selection, sealing performance and isolation reliability.

Typical applications

  • Chemical injection and dosing systems
  • Process isolation in chemical and petrochemical plants
  • Sampling systems for process and quality monitoring
  • Fugitive emissions control at process isolation points
  • Severe service duties involving corrosive or hazardous media

What chemical & petrochemical specifiers need?

Material compatibility with the process media is critical in this sector, alongside sealing performance that can be verified without shutting the process down. As emissions regulations tighten, the sealing performance of valves has moved from a maintenance consideration to a compliance requirement, and specifiers need testing and documentation to match.

Why specify Colson for chemical & petrochemical?

Our engineering team specifies materials, seals and configurations to suit the specific process media and operating conditions of each project, rather than applying generic specifications to critical applications. Full EN10204 3.1 traceability and ISO-certified quality systems are supplied as standard, and where a standard configuration does not meet the application, we design and build bespoke solutions in-house.

Colson Valves has supplied instrumentation and double block & bleed valves into chemical and petrochemical applications for over three decades, meeting exacting material, testing and documentation requirements on every project.

Our experienced engineers are ready to answer your Chemical & Petrochemical queries.

Whether you need a standard product, bespoke solution, or something in between, our team is on hand to discuss your project, help with specification and give you a speedy answer on lead times. We’ve put together a few FAQs here, but anything else please get in touch.

Yes. Our engineering team specifies materials, seals and configurations to suit the specific process media, including corrosion-resistant and exotic alloys where standard materials aren’t suitable.

Yes. We manufacture low-emission valve configurations designed to minimise leakage and support compliance with tightening emissions regulations.

Yes. Our double block & bleed valves allow isolation to be verified via the bleed point without interrupting the wider process.

Every valve is supplied with full EN10204 3.1 material certification as standard, with additional testing available to match your project’s compliance requirements.

Yes. Where a standard configuration doesn’t meet the application, our engineering team designs and manufactures bespoke solutions in-house.
