Which models the PED certificate covers
The Module D1 certificate covers the models and sizes listed in its technical annex, for which Directive 2014/68/EU requires the involvement of a notified body. The table summarizes that annex; the breakdown by body material (EN-GJS-400-18 ductile iron, ASTM A216 WCB carbon steel, and ASTM A351 CF3M or CF8M stainless steel) and by pressure (PN16, PN25, PN40, Class 150, and Class 300) is given in the certificate.
| Models | Fluid | Sizes included in Module D1 |
|---|---|---|
| M1 (reducing) · S1 (excess pressure) · C1 (control) | Group 1 liquids | DN50 to DN150, depending on material and pressure rating |
| M1 · S1 · C1 | Group 1 gases | DN32 to DN150, depending on material and pressure rating |
| M1 · S1 · C1 | Group 2 gases | DN125 and DN150, depending on material and pressure rating |
| M2 and VD (reducing) · S2, S3, and S4 (excess pressure) | Group 1 liquids | DN50 to DN100, depending on material and pressure rating |
| M2 · VD · S2 · S3 · S4 | Group 1 gases | DN32 to DN100, depending on material and pressure rating |
Outside the scope: valves for unstable Group 1 fluids, valves for Group 2 fluids above 350 °C, and M2 and S2 models from DN65 to DN100 with welded Ø175, 195, and 230 mm actuators and an external pressure sensing point.
For all other sizes and pressures, the datasheet and manual for each model state its classification under the directive and whether it carries CE marking. For example, the PRV30 reducing valve (DN15 to DN25, PN25, Group 2 fluids) falls under Article 4.3 and does not require CE marking.
For projects in the United States and Canada, see how our valves meet ANSI, ASME, and ASTM requirements.
Valves for explosive atmospheres (ATEX)
Directive 2014/34/EU governs equipment installed in areas where an explosive atmosphere may occur. Valfonta’s technical file is held in custody by the Laboratorio Oficial J. M. Madariaga (LOM), notified body No. 0163. The latest supplement, from 2023, covers the marking 2G-Ex h IIC TX °C Gb / 2D-Ex h IIIC TX °C Db.
The manuals for the reducing valves and excess pressure valves state the II 2 GD marking: suitable for zones 1 and 2 (flammable gases, vapors, and liquids) and zones 21 and 22 (combustible dust), within the temperature class corresponding to the fluid temperature. Each product page indicates whether the model is available in an ATEX version. More information in ATEX valves: what the regulations require.
Questions about certificates
Which Valfonta valves carry CE marking?
Those that, by size, pressure, and fluid, fall into a risk category under Directive 2014/68/EU. Those included in the technical annex of the Module D1 certificate (M1, M2, VD, S1, S2, S3, S4, and C1 in the sizes indicated) are manufactured under that certificate. Smaller ones, such as the PRV30, may fall under Article 4.3 and do not carry CE marking: the datasheet for each model indicates this.
Can I install the valves in an ATEX zone?
Yes, for models with an ATEX version. The manuals for reducing valves and excess pressure valves state the II 2 GD marking for zones 1 and 21 (and 2 and 22). Tell us the zone and temperature class in your inquiry.
What does the ISO 9001 certificate cover?
Valfonta’s quality management system for the design, manufacture, and sale of globe control valves for process control, in accordance with UNE-EN ISO 9001:2015. It is valid until May 15, 2027.
How do I check that the PED certificate is valid?
The certificate itself states that its validity can be verified with OCA Instituto de Certificación at info.certificacion@ocaglobal.com. The current issue is dated February 23, 2026, and expires on February 26, 2029.
Can I request material certificates with my order?
Yes. Every valve has an individual serial number, which makes it possible to trace its materials and supply the exact spare parts. Request material certificates when you place your order.
Request the documentation you need
If you need a certificate, a declaration of conformity, or the material certificates for an order, tell us the model and, if you have it, the serial number on the nameplate.
