Proportional directional valves type DHZO-AES and DKZOR-AES
direct operated, without position transducer, ISO 4401 size 06 and 10

DHZO-A* and DKZOR-A* are proportional
valves, direct operated without position
transducer, which provide both directional
and non-compensated flow control
according to the electronic reference
signal.
They operate in association with electronic
drivers, see section ,ݘwhich 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:
• -A, without position transducer;
• -AE, -AES as -A plus analogue (AE) or
digital (AES) integral electronics ብ;
The 4-way spool ባ , sliding into a
5-chambers body ቢ, is directly operated
by proportional solenoids ቤ.
The integral electronics ብ ensures factory
presetting, fine functionality plus valve-tovalve interchangeability and simplified
wiring and installation.
The electronic main connector ܭis fully
interchangeable for -AE and -AES
executions.
Standard 7 pin main connector is used for
power supply, analog input reference and
monitor signals.
12 pin connector is used for options /Z and
/W (AES).

MO = horizontal hand lever
MV = vertical hand lever
BMO= horizontal hand lever installed at
side of port A
BMV= vertical hand lever installed at side
of port A

A, B, T, negative overlapping
Spool type (regulating characteristics)
L = linear;
S = progressive;
D = differential-progressive (as S, but with P-A= Q, P-B= Q/2)
Following communication interfaces ቧ, ቨ
are available for the digital -AES execution:
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating through Atos PC software always present also for -BC, -BP and -EH
options.
• -BC, CANopen interface
• -BP, PROFIBUS DP interface
• -EH, EtherCAT interface
The valves with -BC, -BP and -EH
interfaces can be integrated into a fieldbus
communication network and thus digitally
operated by the machine control unit.
The coils are fully plastic encapsulated
with insulation class H.
Mounting surface: ISO 4401 sizes 06 and 10.
Max flow respectively up to 50 l/min and
105 l/min with valve differential pressure
Δp = 30 bar, see table .ݙ
Max pressure = 350 bar for DHZO;
315 bar for DKZOR.
Spool size: 14, 1, 3, 5 = see section ݙ
