LIQZO-TE are 2-way proportional cartridge valves, designed for mounting in manifold blocks which provide proportional not compensated flow control according to the electronic reference signal.

They operate in association with electronic drivers, see section 2, which supply the proportional valves with proper current to align valve regulation to the reference signal supplied to the electronic driver.

They are available in different executions:

  • T, with position transducer ;
  • TE, -TES as -T plus analogue (TE) or digital (TES) integral electronics

The regulation is operated by means of a poppet  with double piloting area, sliding into a sleevel and provided of integral LVDT position transducer .

The poppet is controlled in closed loop by means of a proportional directional valve  type DHZO, see table F160.

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 -TE and -TES executions.

Standard 7 pin main 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 for the digital -TES execution:

  • PS, Serial communication interface for configuration, monitoring and firmware updating through Atos PC 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.
