LICZO, LIMZO and LIRZO are 2-way proportional cartridges with integral or remote pressure transducer which respectively provide pressure compensation, relief and reducing controls according to the electronic reference signals.

They operate in association with electronic drivers, see section 4, which supply the proportional valve with proper current to align valve regulation to the reference signal supplied to the electronic driver. 

These valves are composed by a 2-way cartridge  and by a closing cover  with a pilot proportional pressure relief valve type RZMO, see tab. F010.

They are available in different executions:

  • TERS with integral pressure transducer plus digital electronics  preset in closed loop, featuring improved static and dynamic performances.
  • AERS as -TERS but without integral pressure transducer (predisposed for connection of remote pressure transducer).

The integral electronics ensures factory presetting, fine functionality plus valve-to valve interchangeability and simplified wiring and installation.

The electronic main connector  is fully interchangeable for -TERS and -AERS executions. Standard 7 pin connector is used for power supply, analog input reference and monitor signals. 

12 pin connector is used for option /Z.

Following communication interfaces  are available:

  • PS, Serial communication interface for configuration, monitoring and firmware updating trough Atos PL software
  • BC, CANopen interface
  • BP, PROFIBUS DP interface

The valves with -BC and -BP interfaces can be integrated into a fieldbus communication network and thus digitally operated by the machine control unit.
