Understanding IECEx Certification and Its Critical Role in Hazardous Environments
Yes, Carilovalves can supply valves with IECEx certifications for explosive atmosphere applications. The company, established in 2000, has built over 24 years of manufacturing expertise in industrial ball valves, with documented capabilities in providing certified solutions for global markets requiring compliance with international explosion protection standards.
What IECEx Certification Actually Means for Valve Procurement
IECEx stands for International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. This certification system ensures that equipment manufactured for hazardous locations meets rigorous international safety requirements. When you source valves for environments where flammable gases, vapors, mists, or dusts exist in concentrations that could ignite, IECEx certification becomes non-negotiable.
The IECEx system covers three key areas: equipment certification, repair and overhaul certification, and personnel certification. For valve manufacturers, the equipment certification (IECEx Certified Equipment Scheme) is the most relevant, requiring comprehensive testing against IEC standards such as IEC 60079 for explosive atmospheres.
Carilovalves’ Current Certification Portfolio
Based on publicly available information, Carilovalves maintains the following international certifications:
| Certification Type | Standard Category | Application Scope |
|---|---|---|
| ISO 9001 | Quality Management | Manufacturing process control |
| API 6D | Pipeline Valves | Ball valve design and testing |
| CE Compliance | European Safety | EU market access |
| IECEx (Verified) | Explosive Atmospheres | Hazardous location equipment |
The company’s quality inspection process includes 100% pressure testing for every valve produced, real-time monitoring during manufacturing, and dimensional accuracy verification. This systematic approach supports their capability to meet IECEx technical requirements when specific hazardous location certifications are requested.

Explosion Protection Techniques Applied to Carilovalves Products
For IECEx compliance, valves undergo specific protection methods depending on the hazardous zone classification:
Zone 0/Zone 1 applications require “ia” or “ib” intrinsic safety levels, while Zone 2 allows “ic” protection. The valve construction must prevent ignition sources including sparks, hot surfaces, and static electricity. Carilovalves’ engineering team designs valves with these considerations, incorporating features such as antistatic devices, flame arrester ports, and certified sealing systems.
The protection concepts typically implemented include:
- Ex d – Flameproof enclosure (enclosing the spark source within a housing that can withstand internal explosions)
- Ex e – Increased safety (preventing excessive temperatures and sparks)
- Ex n – Non-sparking equipment (suitable for Zone 2)
- Ex p – Pressurization or purging systems
