Overview

EN 13397:2001 - Industrial valves - Diaphragm valves made of metallic materials - is a European Standard published by CEN that defines design, construction, testing and marking requirements for metallic-shell diaphragm valves. The standard covers flanged, screwed and weld-end valves across specific nominal sizes (DN and imperial sizes) and pressure ratings (PN 6, PN 10, PN 16, PN 25 and Class 150). EN 13397:2001 is intended for use by manufacturers, purchasers and conformity bodies specifying or verifying diaphragm valves in industrial piping systems.

Key topics and technical requirements

• Scope and sizes: Specifies nominal sizes for flanged (DN 10–DN 300), screwed (¼–3 in), and weld-end (DN 8–DN 300) valves and covers PN 6, PN 10, PN 16, PN 25 and Class 150 designations.
• Valve types: Defines weir type and straight-through type diaphragm valves and permissible body patterns (straight or 90° angle).
• Materials: Shell (steels, cast irons, copper alloys) selection references are given; diaphragm and body lining materials are to be agreed between manufacturer and purchaser.
• Pressure–temperature ratings: Body/bonnet ratings follow flange standards; note that diaphragm or lining materials can limit allowable temperature/pressure. Valves must be suitable for -5 °C to +50 °C at rated pressure.
• Operation and actuation: Valves must be operable by handwheel, lever or actuator; clockwise closing is required. Actuator interfaces follow EN ISO 5210.
• Construction details: Requirements for bonnets (stem sealed or non-stem sealed), replaceable diaphragms, isolation of stem and internals from line fluid, bolting per EN 1515-1, visible open/closed indication.
• Functional performance: Shell design strength calculated/tested per prEN 12516 series; seat leakage acceptance Rate A per prEN 12266-1.
• Testing, inspection and marking: Fully assembled valves are pressure tested (lined valves tested after lining). Marking requirements include material/diaphragm IDs, operating direction and any pressure restrictions.

Applications and users

EN 13397:2001 applies where corrosion-resistant isolation between fluid and mechanism is required, including:

• Water and wastewater treatment
• Chemical and process plants
• HVAC and utility services
• Food and pharmaceutical services (when compatible diaphragm/lining chosen) Primary users:
• Valve manufacturers and designers specifying metallic diaphragm valve construction
• Procurement/specification engineers writing tender or purchase documents
• Test laboratories and conformity assessors verifying compliance
• Plant operators selecting valves to meet pressure/temperature and leakage criteria

Related standards

EN 13397 references and complements other norms used for dimensions, testing and materials, for example:

• EN 558 (face-to-face dimensions), EN 1092 (flanges), EN 12516 (shell design strength)
• prEN 12266-1 (valve testing / leakage classes), EN ISO 5210 (actuator interfaces) When specifying diaphragm valves, use EN 13397 together with these referenced standards to ensure full compliance.
