Overview

EN 13789:2010 (CEN) is the European standard that specifies technical requirements for cast iron globe valves used in industrial and general-purpose applications. It covers valves in straight, angle or oblique patterns with flanged or threaded end connections, detailing acceptable nominal sizes, pressure/temperature ratings, materials, testing and marking. The standard supports conformity with the EU Pressure Equipment Directive (97/23/EC) and supersedes EN 13789:2002.

Key topics and requirements

• Scope & sizes
  • Flanged valves: DN 10 to DN 400 (full DN list in the standard).
  • Threaded valves: ½, ¾, 1, 1¼, 1½, 2 inches.
  • Pressure designations: flanged PN 6, PN 10, PN 16, PN 25, PN 40; threaded PN 6, PN 10, PN 16.
• Materials
  • Body/bonnet materials selected from EN 12516-4. PN 40 requires spheroidal graphite cast iron (EN‑GJS).
  • Welding of grey cast iron and impregnation of castings are not permitted.
• Design & dimensions
  • Face-to-face and centre-to-face dimensions for flanged valves per EN 558; threaded ends per ISO 7-1 (Rc/Rp).
  • Body port inside diameters specified (Table 1) and full/reduced bore options allowed.
• Operation & actuator interface
  • Standard supply with handwheel; attachments for multi-turn actuators per EN ISO 5210.
  • Closing direction: clockwise when viewed from above. Handwheel sizing per EN 12570.
• Functional performance
  • Shell design strength: calculation (EN 12516-4) or experimental verification per EN 12516-3.
  • Seat tightness: Rate A (EN 12266-1). Back seat tightness: Rate C (EN 12266-2).
  • Allowable differential pressures defined (Table 2) and rules for isolation/regulating use.
• Testing & compliance
  • Manufacturer pressure testing required (EN 12266-1). Additional EN 12266-2 tests optional (F21 excluded).
  • Valves must be marked and accompanied by declaration of compliance referencing EN 13789.

Applications and who uses it

• Relevant for:
  • Valve manufacturers and foundries producing cast iron globe valves.
  • Specifiers, piping engineers and procurement teams writing technical specifications for industrial plants.
  • Testing laboratories, quality inspectors and certification bodies performing compliance and pressure tests.
  • Plant operators and maintenance teams selecting valves for water, steam, gas or other line media where cast iron valves are suitable.
• Typical uses: isolation and regulating duties in industrial, municipal and general-purpose piping systems where cast iron's properties and the covered PN/DN ranges meet operational requirements.
