Overview

EN 1984:2010 - Industrial valves: Steel gate valves is the CEN European Standard that specifies design, materials, dimensions, testing and marking requirements for steel gate valves (wrought, cast or fabricated) with flanged, butt-welding, socket-welding or threaded end connections. It applies primarily to industrial and general-purpose applications and covers a wide range of nominal sizes (DN) and pressure designations (PN and Class).

Key topics and technical requirements

• Scope & sizes: Covers DN 8 through DN 1000 (DN 750 limited to Class-designated valves). Note: DN 8 and DN 12 are not used for flanged ends; socket-weld and threaded ends are limited to DN 8–DN 65.
• Pressure designations:
  • Flanged & butt-weld valves: PN 10, PN 16, PN 25, PN 40, PN 63, PN 100 and Class 150, 300, 600.
  • Socket-weld & threaded valves: PN 10–PN 100 and Class 600, Class 800 (Class 800 is an intermediate class common for socket/threaded ends). The standard provides rules for deriving the appropriate Class 800 ratings from Class 600.
• Materials & trim:
  • Body, bonnet and cover materials selected from EN 12516-1 material groups.
  • Internal wet parts must have corrosion resistance at least equal to body/bonnet.
  • Stem materials: forged/drawn/rolled with corrosion resistance at least equivalent to a ferritic steel containing 13% chromium.
• Dimensions & end connections:
  • Face-to-face and end-to-end per EN 558 (flanged) and EN 12982 (butt weld); socket-weld per EN 12760.
  • Flanged ends per EN 1092-1 (PN) or EN 1759-1 (Class); threaded alternatives per ISO/ASME thread standards.
• Operation & attachments:
  • Outside-screw stem by default; handwheel supplied unless actuator attachment per EN ISO 5210 is specified.
  • Closing direction: clockwise viewed from above; handwheel marking per EN 19.
• Testing & performance:
  • Pressure and seat leakage testing per EN 12266-1 and EN 12266-2 with seat leakage acceptance rates (A for elastomeric/polymeric, B for other seatings; backseat Rate C).
  • Shell strength verification per EN 12516 (parts 1–3) or by elevated pressure testing.
• Manufacture & welding:
  • Welding procedures per EN ISO 15607; welders/operators approved per EN 287-1 / EN 1418; NDT and heat treatment per approved procedures.

Applications

• Specification and procurement of industrial steel gate valves for water, steam, oil, gas and general industrial services.
• Use in piping systems requiring defined DN sizes, PN/Class pressure ratings, and verified materials and leak performance.
• Basis for manufacturer conformity, testing, QA, and installation documentation.

Who uses this standard

• Valve manufacturers and designers
• Procurement and specification engineers
• Plant operators, maintenance and inspection teams
• Test laboratories and conformity assessors
• Regulatory and compliance professionals
