The following product groups are part of the certification:

  • Mechanically actuated valves

  • Pneumatically operated valves
  • Pilot operated solenoid valves

Valves without a safe position are just part of the assessment report (systematic capability), including:

Products made from stainless steel, for low temperature as well as those for explosion hazardous environment have been certified too.
