Advantages of integrated controls

@ the engineering stage

  • Money and time saver (turn-key solution)
  • Designed by an actuator specialist
  • Safety (integrated protections)
  • Compact design
  • Bus compatible

@ the installation stage

  • Money and time saver (limited wiring works)
  • Makes life easier in case of multiple units installations: Standardised and well documented design

@ the commissioning stage

  • Only a power supply wiring is necessary to perform the preliminary motorised valve tests on site
  • With the local control keypad, valve adjustments can be done by a single person at the valve location

Once in operation

  • With the keypad, local control is possible (for valve periodic checking i.e)
  • If some changes occur on the process most of the parameters can be changed via a simple switch / programming
  • The site maintenance department can hold only a couple of boards on stock even if hundred of actuators are installed (standard design)
  • Informations for the maintenance team
