Introduction
In today’s demanding industrial environments, safety and reliability are more critical than ever. Whether operating in offshore platforms, petrochemical refineries, or marine industries, plant operators rely on instrumentation and control systems that perform flawlessly under pressure. This is where internationally recognized certifications such as SIL (Safety Integrity Level) and ATEX (Atmospheres Explosibles) play a vital role. At Nordenflow, we ensure that our automation solutions not only meet performance expectations but also comply with the highest safety and compliance standards.
What is SIL?
Safety Integrity Level (SIL) is a measure of risk reduction provided by a safety function. It is defined under the international standard IEC 61508 and widely used in industries where safety is paramount. SIL is classified into four levels (SIL 1 to SIL 4), with SIL 4 providing the highest degree of safety.
In valve automation and control systems, SIL certification confirms that actuators, positioners, and solenoid valves are tested and proven to perform critical shutdown functions when required.
- SIL-rated systems reduce the probability of failure on demand (PFD).
- Typical applications include Emergency Shutdown Valves (ESDVs), Blowdown Valves (BDVs), and Fire & Gas Safety Systems.
By integrating SIL-compliant components, Nordenflow helps clients enhance plant safety while maintaining regulatory compliance
What is ATEX?
ATEX certification originates from the European Union and applies to equipment intended for use in explosive atmospheres. The name derives from the French phrase “ATmosphères EXplosibles”.
Industrial sites such as oil and gas facilities, LNG plants, and chemical refineries often contain hazardous areas where flammable gases, vapors, or dust are present. ATEX-certified equipment ensures safe operation in these environments by preventing ignition risks.
For valve automation and instrumentation, ATEX compliance is especially important in:
- Solenoid valves and regulators operating in hazardous zones.
- Positioners and control systems mounted directly on valves in explosive atmospheres.
- Automation solutions where safety and explosion protection are non-negotiable.
At Nordenflow, we supply products designed to meet ATEX requirements, ensuring reliability and peace of mind in even the most challenging conditions.
Why SIL and ATEX Compliance Matters
The importance of these certifications goes beyond regulatory requirements:
- Enhanced Safety – Protects personnel, assets, and the environment.
- Operational Reliability – Ensures valves and actuators respond precisely when demanded.
- Regulatory Compliance – Meets EU and international standards, reducing legal and operational risks.
- Customer Trust – Demonstrates a commitment to delivering high-quality, certified solutions.
When both SIL and ATEX standards are combined, plant operators can be confident that their systems are equipped to handle critical shutdowns while operating safely in hazardous environments.
