Overview

EN 60534-6-2:2001 - Industrial-process control valves: Part 6-2 - specifies standard mounting details for attachment of positioners to control valves, focusing on positioner mounting on rotary actuators. Adopted from IEC 60534-6-2:2000 and published by CLC/CENELEC, the standard enables interchangeability between actuators and positioners by defining mechanical interfaces, feedback connections and basic mounting arrangements.

Key topics and technical requirements

• Mounting interface
  • Requires a drilled, plane mounting surface perpendicular to the rotary part axis (as shown in the standard’s basic and universal designs).
  • Two mounting options: a basic design (simple interface) and a universal design (more variations for positioner adaptation and feedback).
• Rotary travel limitation
  • Applies to rotary actuators whose rotary part has a maximum travel of 90°; direct feedback rotation coincides with valve angular travel.
• Feedback connection
  • Positioner must provide means to connect moving parts to the shaft or shaft extension. Design should minimize lost motion and allow for thermal linear expansion up to 1 mm of the rotary part.
• Mounting accessories and fastening
  • Unless otherwise specified, positioner manufacturers supply two or more M6 screws (plus nuts and washers) to secure the positioner to the actuator.
• Manufacturing details
  • Shaft end may be square or round (flats not required for round shaft ends). Multiple drilling patterns accommodate various housing sizes and masses.
• Durability considerations
  • Mounting and feedback connections must take vibration resistance into account.

Applications and who uses this standard

• Valve and actuator manufacturers use EN 60534-6-2 to design actuators with standardized mounting pads and shaft features for wide positioner compatibility.
• Positioner manufacturers reference the standard when designing housings, feedback linkages and supplying mounting hardware.
• Plant engineers, procurement and maintenance teams use it to ensure interchangeability, simplify spare parts management, and enable retrofit upgrades of control valves in process industries (chemical, petrochemical, power, water treatment, etc.).
• Valve assembly shops and integrators adopt the mounting dimensions and drilling patterns to reduce assembly time and avoid custom adaptors.

Related standards

• IEC 60534-6-2:2000 (identical international text)
• Other parts of the IEC/EN 60534 series for definitions and broader valve performance/terminology

EN 60534-6-2:2001 is essential when specifying mechanical interfaces for positioners on rotary actuators, enabling standardized, vibration-resistant, and interchangeable assemblies across industrial-process control valves.
