Norsk Offshore Valves & Flow Control
Valves, actuation and flow-control solutions for offshore, oil & gas, petrochemical, marine, power generation and process applications worldwide.
Norsk Offshore provides a comprehensive range of valves and flow-control equipment for process piping, pipelines, utilities and mechanical systems operating in demanding environments.
Our portfolio covers isolation, throttling, non-return, pressure protection and automated flow-control applications, with equipment available in carbon steel, alloy steel, stainless steel, duplex, super duplex, nickel alloys and other specialist materials.
Products can be sourced to recognised international standards and selected according to valve type, size, pressure class, material, end connection, process conditions and service medium. We support individual replacement requirements as well as larger valve packages for new projects, maintenance programmes, plant shutdowns and system modifications.
Manual, pneumatic, electric and hydraulic actuation can also be accommodated where required, together with accessories, certification, inspection and testing, export packing and international logistics.

Technical Procurement & Project Support
Valve selection depends on operating and design parameters including valve type, size, pressure class, material, end connection, process medium, temperature and required function. For automated and control applications, actuator type, fail position, control signal and associated accessories may also need to be specified.
Our team can assist with:
- Isolation, Control & Non-Return Valves
- Safety & Pressure Relief Valves
- Manual & Actuated Valve Packages
- Carbon, Alloy & Stainless Steel Materials
- Duplex, Super Duplex & Specialist Alloys
- Valve Identification & Cross-Reference Review
- Project, Maintenance & Shutdown Procurement
- Certification, Inspection & Testing Coordination
- Replacement & Urgent Requirements
- Export Packing & Worldwide Logistics
For larger piping packages, valves can be coordinated with pipes, tubes, flanges, fittings and fasteners, allowing related materials to be consolidated within a coordinated procurement package.
Documentation & Certification
Documentation can be provided according to the valve type, manufacturer, material specification and project requirements.
This may include material test certificates, pressure-test documentation, inspection reports, dimensional records, valve datasheets and applicable manufacturer certification.
Requirements for third-party inspection, fire-safe design or testing, fugitive-emission performance, sour service, material traceability or other project-specific approvals should be identified at RFQ stage.
