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).

Coil voltage (only for -A execution)
see section ‫:ݜ‬
- = standard coil for 24VDC Atos drivers
6 = optional coil for 12VDC Atos drivers
18 = optional coil for low current drivers
Hydraulic options, see section ‫:ݚ‬
B = solenoid and integral electronics at
side of port A
Y = external drain
Options for -A execution see section ‫:ݜ‬
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
N = manual micrometric adjustment
NV = as N plus handwheel and graduated

7 = 3 position, spring centered
Spool overlapping in central position, see section ‫ݙ‬
1 = P, A, B, T positive overlapping (20% of spool stroke)
3 = P positive overlapping; (20% of spool stroke)
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
