ATOS LIQZO-L 3 Way Proportional Cartridge Valve With Doubleposition Transducer

Product Description:

LIQZO-L*and LlQZP.L* * are 3-way pro.portional cartridge valves, with doubleposition transducer designed for moun-ting in mainfold blocks which provideboth directional and non compensateclow coniro accorcing to elecironic reterence signal.

They operate in association with electronicdrivers,see section g,which supply theproportional valves with proper current toalign valve regulation to the referencesignal supplied to the electronic driver.Thay are available in diflerent executions..-L,with two integral posilion transducers0.0’-LE,-LES as -l plus analogue (LE)ordigital (LES) integral electronics (5.The regulation is operated by means of aspool ) with double piloting area slidinginto a sleeve 2)and provided of integraLVDT position iransducer (③).
