Cartridges valves

ISO sizes 16, 25, 32, 40, 50, 63, 80, 100

  • Flow to 10.000 l/min
  • Pressure to 350 bar

A full line of cartridge valves composed by a poppet or spool cartridge and by a functional cover that retains the ISO cartridge into properly machined blocks and provides hydraulic piloting. On-off or proportional function according to the modular composition of functional covers.

Cartridge models

normally closed for relief/pressure compensator/directional/check controls

normally open for pressure compensator/directional/check controls

spool type for pressure reducing function

LIQZO proportional cartridges



LIQZO-LE are 2-way or 3-way proportional cartridges with integral electronics providing high flow control in high dynamics, according to reference signals.

Double closed-loop control by two position transducers on main spool and servoproportional pilot to guarantee fast response times, high dynamics and regulation accuracy.

All proportional cartridges are in "rugged" execution to withstand high vibrations and mechanical stresses.
