Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 5: Control valves

This part of the standard determines the special requirements and tests to be applied to control valves for a range PN 6 to PN 25, the nominal dimensions of which are as defined in Part 1. The Type tests shall be carried out on valves of DN <= 500, by agreement between the supplier and purchaser, for higher DNs. This Part 5 does not deal with the performance of control valve accessories whether or not these form an integral part of the valves.

Armaturen für die Wasserversorgung - Anforderungen an die Gebrauchstauglichkeit und deren Prüfung - Teil 5: Regelarmaturen

Diese Norm legt die besonderen Anforderungen und Prüfungen für Regelarmaturen für einen Druckbereich von PN 6 bis PN 25 fest, deren Nennweiten in Teil 1 bestimmt sind. Typprüfungen sind an Armaturen mit DN <= 500 durchzuführen, bei größeren Nennweiten im Einvernehmen zwischen Lieferant und Abnehmer. Diese Norm behandelt nicht die Leistungsmerkmale von Zubehör- oder Anbauteilen der Armaturen unabhängig davon, ob sie integraler Bestandteil sind oder nicht.

Overview

EN 1074-5:2001 is a CEN standard that sets the fitness for purpose requirements and appropriate verification tests specifically for control valves used in water supply systems. It applies to control valves with pressure ratings PN 6 to PN 25 and to nominal dimensions as defined in EN 1074‑1. The standard specifies that type tests are to be carried out on valves of DN ≤ 500, with higher diameters tested by agreement between supplier and purchaser. EN 1074-5:2001 does not cover the performance of control valve accessories, whether integral or not.

Key topics and requirements

• Scope of application: Control valves for water supply in the PN 6–PN 25 pressure range and nominal dimensions per Part 1.
• Fitness for purpose: Requirements focused on ensuring valves meet intended functional use in water distribution and control.
• Verification tests: Special tests and criteria to verify compliance; type testing obligations for valves up to DN 500 (higher DNs by agreement).
• Exclusions: Performance of accessories (actuators, sensors, pilot devices) is explicitly excluded from this part.
• Manufacturer / purchaser agreement: Provisions for testing arrangements on larger-diameter valves (DN > 500) to be agreed contractually.

Applications and users

EN 1074-5 is practical for professionals involved in the specification, procurement, manufacture, testing and operation of control valves in water supply systems:

• Valve manufacturers - design compliance and type test planning.
• Suppliers and purchasers - contractual verification, acceptance testing and quality assurance.
• Water utilities and network operators - selection and installation specification for control equipment.
• Consulting and design engineers - system design, performance assurance and tender documents.
• Test laboratories - executing verification tests and issuing compliance reports.
• Regulators and standards bodies - harmonized baseline for safety and reliability.

Related standards

• EN 1074 series (Part 1 is referenced for nominal dimensions).
• Other EN standards on valves and water supply systems may complement EN 1074-5 for materials, accessories and detailed performance testing.

EN 1074-5:2001 is essential reading when specifying or procuring control valves for potable and non-potable water distribution where conformity, type testing and clear contractual testing clauses are required. Keywords: EN 1074-5, control valves, water supply, PN 6–PN 25, DN ≤ 500, type tests, fitness for purpose.
