MA-DPZO-T(ES) Hydraulic Proportional Valve flow 600L/min , pressure 350bar
DPZO-T* are two stage hydraulic proportional valves
with position transducer on the main
spool which provide both directional and
non compensated flow control according
to electronic reference signal.
They operate in association with electronic
drivers, see section , which supply
the proportional valves with proper current
to align valve regulation to the reference
signal supplied to the electronic
They are available in different executions:
• -T, with position transducers ;
• -TE, -TES as -T plus analog (TE) or
digital (TES) integral electronics .
The 4-way spool , sliding into a
5 - chambers body , is piloted by a
proportional directional valve type
DHZO (see tab. F160) and it is controlled
in closed loop position by means of the
LVDT transducer .
The pressure reducing valve with fixed
setting ensures a costant piloting
The integral electronics ensures
factory presetting, fine functionality
plus valve-to-valve interchangeability
and simplified wiring and installation.
The electronic main connector is fully
interchangeable for –TE and –TES
Standard 7 pin main connector is used
for power supply, analog input reference
and monitor signals.
12 pin connector is used for options /Z
The special /S* options add a closed
loop control of pressure (/SP) or force
(/SF and /SL) to the basic closed loop
spool position one.
Following communication interfaces
are available for the digital -TES
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating through Atos PC software
• -BC, CANopen interface
• -BP, PROFIBUS DP interface
The valves with -BC and -BP interfaces
can be integrated into a fieldbus
communication network and thus digitally
operated by the machine control unit.
The coils are fully plastic encapsulated
(insulation class H) and the valves have
antivibration, antishock and weather-proof
Mounting surface: ISO 4401 sizes 10, 16,
25 and 32.
Max flow respectively up to 160 l/min, 430
l/min, 680 l/min, 730 l/min and 1100 l/min
with valve differential pressure Δp = 30
bar, see table .
Max pressure: 350 bar.
