This document specifies the characteristics of valves made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels.

It is applicable to isolating unidirectional and bi-directional valves with spigot ends or electrofusion sockets intended to be fused with PE pipes or fittings conforming to prEN 1555-2:2024 and prEN 1555-3:2024 respectively.

Valves made from materials other than PE, designed for the supply of gaseous fuels conforming to the relevant standards can be used in PE piping systems according to prEN 1555 (all parts), provided that they have PE connections for butt fusion or electrofusion ends, including integrated material transition joints, conforming to prEN 1555-3:2024. It also specifies the test parameters for the test methods referred to in this document.

In conjunction with Parts 1, 2, 3 and 5 of EN 1555, it is applicable to PE valves, their joints and to joints with components of PE and other materials intended to be used under the following conditions:

a) a maximum operating pressure, MOP, up to and including 10 bar1 at a reference temperature of 20 °C for design purposes; NOTE 1 For the purpose of this document and the references to ISO 8233, MOP is considered to be nominal pressure.

b) an operating temperature between −20 °C to 40 °C.

NOTE 2 For operating temperatures between 20 °C and 40 °C, derating coefficients are defined in EN 1555-5. EN 1555 (all parts) covers a range of maximum operating pressures and gives requirements concerning colours.

NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. This document covers valve bodies designed for connection with pipes with a nominal outside diameter dn ≤ 400 mm. 

This document specifies basic requirements for hydraulic part-turn valve actuators, both double acting and single acting, used for on-off and modulating control duties. It includes guidelines, recommendations and methods for enclosure and corrosion protection, control and testing. It does not apply to hydraulic actuators which are integral parts of control valves and to hydraulic actuators designed for permanent immersion in fresh or sea water as well as electro-hydraulic actuators. Other requirements, or conditions of use, different from those indicated in this document can vary upon request.

This document provides requirements for metallic mounting kits for part-turn valves and actuator attachments. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm (up to F30 flange type). It applies to mounting kits for part-turn valves and actuators with integral attachment flanges and drive components as described in ISO 5211 (see Figure 1), when direct mounting of the actuator on valve is not practical. Figure 1 illustrates the two different types of mounting kits in the scope of this document. Stacking of mounting kits/intermediate supports is not within the scope of this document. This document specifies methods for design and environmental corrosion protection. When a reference is made to this document, all the requirements apply, unless otherwise agreed between the purchaser and the manufacturer/supplier, prior to order. In this document, the term "valve" covers valve or shaft extension top-flange, and the term “actuator” covers part-turn actuator or combination of multi-turn actuator and gearbox. Control valves are excluded from this document.

EN 13611:2019, Clause 1 applies with the following modification and addition: Modification: The 1st paragraph of EN 13611:2019, Clause 1 is replaced by: This document specifies the safety, design, construction, and performance requirements and testing for multifunctional controls for burners and appliances burning one or more gaseous fuels, hereafter referred to as ‘MFC’. This document is applicable to MFCs with declared maximum inlet pressures up to and including 50 kPa and nominal connection sizes up to and including DN 150. The 4th paragraph of EN 13611:2019, Clause 1 is removed. Addition: This document is applicable to MFCs consisting of two or more functions, at least one of which is a mechanical control, as specified in the relevant control standard (see Figure 1). This document is not applicable to MFCs consisting only of electronics (an example is a combination of functions according to EN 298:2022 and EN 1643:2022).
