Permanent impermeability monitoring of the stem sealing of valves

Author: Samuel Weber Manfred Goßmann


Main issues

  • Permanent monitoring of the tightness of the stem sealing
    • Not only as a snapshot under testing conditions or under operation conditions elaborately with sniffing equipment
    • Monitoring in all operating conditions (independent of media, process pressure, process temperature, process-related load changes, …)
  • Apllicability of the system to all quarter turn valves
    • Comparability of various valve types of various valve manufacturers
    • Independence of tests and certificates of manufacturers and inspection companies
