WG 3.4 Control Valve

Focus

The "Control Valve" working group addresses issues including the following topics in the context of its experience exchange, concept developments, formulation of requirements to be met by automation solutions and its involvement in national and international standardisation:

  • Determination of requirements specially pertaining to control valves used in the chemical industry
  • Market monitoring, evaluation of innovations
  • Organisation and evaluation of type testing
  • Representation of operator interests with respect to manufacturers
  • Harmonisation of device operation and planning
  • Diagnostic options through digital positioners and intelligent limit switches
  • Evaluation of the effects of the Machinery Directive and other regulations on control valves
  • Design recommendations for actuators to be mounted on on/off valves
  • Selection criteria for different control valve types

Advantages

  • Identification of economic potential where control valves are used (e.g. selection of the optimum control valve type relative to process engineering constraints)
  • Active influencing of norms and standards to safeguard user interests and avoid more costly standards
  • Influencing the development of equipment with regard to technology, procurement and maintenance costs, taking uniform requirements into consideration
  • Increasing of plant availability and extension of inspection deadlines through the use of diagnostic systems
  • The exchange of experience avoids duplication of efforts
