PED, ATEX and SIL, The European Compliance Pack
Three different requirements get bundled into one phrase on a European enquiry. They are not the same thing, and they are issued by different bodies.
PED, ATEX and SIL, The European Compliance Pack
A European project enquiry often asks for a valve that is PED compliant, ATEX compliant and SIL rated. These come from three separate pieces of legislation and one standard, are issued by different bodies, and mean different things for the valve. Treating them as a single tick is how orders go wrong.
PED governs the pressure equipment itself. ATEX governs equipment used in a potentially explosive atmosphere, which in practice reaches the instrumentation and the actuator rather than the bare valve body. SIL is a functional safety capability of a safety function, not a badge that can be applied to a valve in isolation.
PED 2014/68/EU, the pressure equipment directive
PED classifies pressure equipment into categories based on the fluid, the pressure and the volume or bore, and the category determines the conformity assessment route. Valve assemblies on European projects are usually placed in a category once the service and the size are known.
Module H is the full quality assurance route, under which a notified body audits the manufacturer's quality system rather than examining each individual valve. Our CE documentation is issued under Module H by Prvá Zváračská, a.s. of Bratislava, Slovakia, acting as notified body 2195, and the current certificate runs from 2026.06.29 to 2029.06.28.
ATEX 2014/34/EU, explosive atmospheres
ATEX applies to equipment placed in a potentially explosive atmosphere, and it is separated into equipment groups and zones. For a valve assembly, the question is usually about the actuator, the solenoid, the position switch and the stem sealing arrangement, not about the body casting.
Our ATEX documentation is issued by Ente Certificazione Macchine (ECM) in Italy. A buyer should check that the certificate covers the assembly as supplied, with the specific actuator and accessories, rather than a bare valve that does not match what is being delivered.
SIL, functional safety, and what it is not
SIL is a safety integrity level under IEC 61508, and it attaches to a safety function, not to a product. A valve can be SIL capable, meaning it has the design features, materials and documentation that a SIL assessment can credit, but the SIL number for a loop is confirmed by the system integrator's analysis.
This distinction matters commercially because a claim of "SIL certified valve" is misleading. We describe our products as SIL capable, which is the accurate statement, and we support the loop assessment with the material and test documentation the analysis asks for.
Three Requirements, Three Answers
| Item | Detail | Note |
|---|---|---|
| PED 2014/68/EU | The pressure equipment and its conformity route | Module H, notified body 2195, valid to 2029-06-28 |
| ATEX 2014/34/EU | Equipment for explosive atmospheres, mainly actuation and instrumentation | Issued by ECM, Italy |
| SIL / IEC 61508 | A capability of a safety function, confirmed in the loop assessment | SIL capable: design, materials and records support the assessment |
| API 6D-1832 | Pipeline valve specification | Certificate valid to 2027-07-26 |
| ISO 9001 / 14001 / 45001 | Management systems | Issued by CQC, China Quality Certification Centre |

Questions this page answers
Conformity under PED is linked to the equipment category, which depends on the fluid, pressure and size. State the service and the size so the applicable category and route can be confirmed against the certificate scope.
No. SIL attaches to a safety function in a loop, confirmed by the system integrator's assessment. A product can be SIL capable, meaning it supports that assessment, but the SIL number is not a product badge.
API 6D certification is held as certificate 6D-1832; the CE PED Module H documentation is issued by Prvá Zváračská, notified body 2195; ATEX is issued by ECM in Italy; and the ISO management system certificates are issued by CQC. All are listed with numbers and validity on the certificates page.
