Maintenance programs

Netherlocks guarantees at least 10 years lifetime of the valve interlock and this is backed by TUV testing and certification. The simple and reliable mechanical design has proven itself over 20 years in the field. While using your system you may find after some time that part of the system was modified, components may be missing, items may have been damaged and exposed to severe stress and vibrations or chemically exposed or fouled. Hence regular condition monitoring and maintenance is required in order to ensure 100% availability. Moreover, valve interlocks may need to be reset due to wear and tear of the valve.

  • Every 1-3 years depending on criticality of the system
  • Survey Certificate

Functional check

  • Visual inspection of locks and cabinets (Survey)
  • Functionality test of locks and sequences (includes resetting of locks if necessary)
  • Every 1-3 years depending on criticality of the system
  • Functional Compliance Certificate

Internal inspection

  • Removal and opening of locks, inspection and cleaning of lock internals (this should be done when locks are exposed for a period of time to severe climates or fouling environments)
