Overview

EN 12288:2010 is the CEN (European) standard for industrial valves - copper alloy gate valves. It defines design and performance requirements for copper-alloy gate valves intended for general use with flanged, threaded, capillary, compression or loose nut/union body ends. The standard covers materials, pressure/temperature ratings, dimensions, test procedures and marking for valves in the nominal size range DN 8 to DN 500 (nominal diameters 8 mm to 110 mm) and pressure designations PN 6 to PN 63 plus Class 150 and Class 300.

Key topics and technical requirements

• Scope and classification
  • Applicability by body-end type (flanged, threaded, capillary, compression, loose nut/union) and nominal size relationships (DN/NPS).
• Materials
  • Requirements for copper alloys, castings and forgings used for bodies, obturators and seats (see normative Annex A).
• Pressure/temperature ratings
  • Designation tables for metallic and non-metallic seats; limitation by PN and Class (Annex B).
• Dimensions and interfacing
  • Face-to-face and centre-to-face dimensions for flanged valves and compatibility with common flange standards.
• Functional performance and strength
  • Shell design strength, obturator strength, seat and shell tightness, flow characteristics and sizing of operating elements.
• Testing and conformity
  • Production pressure testing, applicability of gas tests, test durations and acceptance criteria (references to EN 12266 series).
• Marking, documentation and storage
  • Mandatory and supplementary markings, declaration of compliance, preparation for storage and transport.
• Regulatory alignment
  • Informative Annex ZA links the standard to EU Pressure Equipment Directive (PED) requirements where applicable.

Practical applications and who uses it

• Manufacturers of copper alloy gate valves use EN 12288:2010 to design, test and mark products for European markets.
• Valve purchasers, specifiers, OEMs and system integrators in plumbing, heating, industrial fluid systems, HVAC and marine applications use the standard to ensure compatibility (DN/PN/Class), material suitability and performance.
• Inspection and testing houses, certification bodies and regulatory authorities reference this standard when assessing conformity, especially where valves are used for drinking water, gas or other regulated services (additional performance or regulatory approvals may be required).

4.1.4 Valve series Two series of valves are specified, series A for flanged and threaded end valves and series B for flanged, threaded, capillary, compression and loose nut/union end valves. Series A valves have the shell components constructed from the restricted range of copper-aluminium and copper-tin alloys (see Table A.1) specified in EN 1092-3 and EN 1759-3, and are suitable for the pressure/temperature ratings given in these two flange standards. Additional copper-aluminium and copper-tin alloys are specified in Table A.1 for series A valves and the pressure/temperature ratings for valves in these materials are the same as given in EN 1
