Overview

EN 60534-3-2:2001 specifies standardized face-to-face dimensions for rotary industrial-process control valves, excluding wafer butterfly valves. The standard covers segmental ball, eccentric rotary plug and barstock globe valves, with both flanged and flangeless designs in nominal sizes DN20 to DN400. Its purpose is to support consistent piping layout, installation planning and interchangeability across manufacturers.

Key Topics

  • Scope: Applies to segmented ball and eccentric rotary control valves (with or without flanges). Wafer butterfly valves and valves with welded or threaded ends are excluded.
  • Nominal sizes: DN20 through DN400.
  • Pressure designations: PN10, PN16, PN20, PN25, PN40, PN50, PN63, PN100, PN110 (notes on correspondence with ISO/ANSI classes are provided in the standard).
  • Flange type: Only raised-face flanges are covered; flangeless control valves (installed by clamping between pipe flanges) are explicitly defined.
  • Dimensions and tolerances: The standard gives overall face-to-face lengths (dimension L) and allowable tolerances for each DN. Dimensions do not include gasket allowances.

Examples of face-to-face dimensions (from the standard):

  • DN20 - L = 76 mm (±2 mm)
  • DN25 - L = 102 mm (±2 mm)
  • DN50 - L = 124 mm (±2 mm)
  • DN100 - L = 194 mm (±2 mm)
  • DN300 - L = 338 mm (±3 mm)
  • DN400 - L = 400 mm (±3 mm)

(Refer to the full table in the standard for all nominal sizes and tolerances.)

Applications

EN 60534-3-2:2001 provides practical value across engineering, procurement and maintenance activities:

  • Piping design and layout: Use standardized face-to-face lengths when specifying pipeline spacing and supports.
  • Equipment interoperability: Ensures replacement valves from different manufacturers fit existing flange patterns and face-to-face spacings.
  • Installation planning: Clarifies dimensions for both flanged and flangeless valves to reduce field adjustments.
  • Procurement and QA: Provides measurable acceptance criteria (L and tolerances) for supplier verification and inspection.

Note: dimensions exclude gasket thickness; allowances should be added during detailed piping design.

Related Standards

  • IEC/EN 60534 (other parts) - broader series on industrial-process control valves
  • ISO 6708 - Pipework components: nominal size (DN) definitions
  • ISO 7005 / EN 1092 - Metallic flanges and flange joints
  • ISO 7268 - Pipe components: nominal pressure definitions

By aligning valve specifications with EN 60534-3-2:2001, design teams and asset owners improve compatibility, simplify valve replacement and reduce installation risk. For complete tables, figures and normative annexes (e.g., Annex ZA), consult the full standard document.
