CVA fits almost to all linear and quarter-turn applications where precise control is demanded. It improves quality and capacity because of the precision and there is no need for compressed air. Actuator is very easy to use and Bluetooth is used in communicating.

  • Supply: 1-phase or DC
  • Linear CVL
  • Quarter-turn CVQ
  • 4-20mA control as standard, network control optional
  • On loss of main power supply the CVA can move to any preprogrammed position. Power is provided by super capacitors
  • Continuous unrestricted modulation duty – S9 (resolution 0,1%)
  • WT IP68 and Eex enclosures
  • Optional manual override
