Servo proportional valves - 5319 Servoproportional valves type DLHZO and DLKZOR
sleeve execution, direct operated, with position transducer, ISO 4401 size 06 and 10
DLHZO and DLKZOR are highperformance servoproportional valves,
direct operated, with sleeve execution and
LVDT position transducer, which provideboth directional and non compensatedflow control according to the electronic
reference signal. They operate in association with electronicdrivers, see section , which supply theproportional valves with proper current toalign valve regulation to the referencesignal supplied to the electronic driver.They are available in different executions:•-T, with integral position transducer ;•-TE, -TES as -T plus analog (TE) ordigital (TES) integral electronics .The 4-way spool for maximum overlapping accuracy.The sleeve is sliding into aprecision - machined and hardened sleeve is mechanically forced into a5-chambers body . The spool is directlyoperated by a proportional solenoids

andit is controlled in closed loop position bymeans of the LVDT position transducer .The integral electronics ensures factorypresetting, fine functionality plus valve-to-
valve interchangeability and simplifiedwiring and installation.The electronic main connector is fullyinterchangable for -TE and -TESexecutions.Standard 7 pin main connector is used forpower supply, analog input reference and
monitor signals.

12 pin connector is used for options /Z
and /S*.
Hydraulic options, see section : B =solenoid, integral electronics andposition transducer at side of port A
The special /S* options add a closed loopcontrol of pressure (/SP) or force (/SF and/SL) to the basic closed loop spool posi-tion one.
Communication interfaces (only for TES) PS = RS232 serial Y =external drain BC = CANbus BP = PROFIBUS-DP Electronics options, for -TE executionsee section : F =fault signal
Following communication interfaces areavailable for the digital -TES execution:•-PS, Serial communication interface. Thevalve reference signal is provided with
analogue commands •-BC, CANopen interface•-BP, PROFIBUS DP interfaceThe valves with -BC and -BP interfaces
can be integrated into a fieldbuscommunication network and thus digitallyoperated by the machine control unit.The coils are fully plastic encapsulated(insulation class H) and the valves have
antivibration, antishock and weather-proof
features.
