Proportional flow valves type QVHZO-AES, QVKZOR-AES
pressure compensated, direct operated, without position transducer, ISO 4401 size 06 and 10
Table F410-16/E
QVHZO and QVKZOR are 2 or 3 flow pro-
portional valves, direct operated without
position transducer, which provide com-
pensated flow control according to the
electronic reference signal.
They operate in association with electronic
drivers, see section
쪨
which supply the
proportional valves with correct current
signal to align valve regulation to the refe-
rence 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;
The flow is controlled by a throttle ,
directly operated by the proportional sole-
noid . The mechanical pressure com-
pensator keeps a constant Δp across
the throttle , thus the regulated flow is
indipendent to the load conditions.
The integral electronics
ensures factory
presetting, fine functionality plus valve-to-
valve interchangeability and simplified
wiring and installation.
The electronic main connector
is fully
interchangable for -AE and -AES executions.
Standard 7 pin connector is used for power
supply, analog input reference and monitor
signals.
12 pin connector is used for option /Z and
option /W (AES).
Following communication interfaces
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 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
with insulation class H.
Surface mounting: ISO 4401, size 06 and 10.
Max flow respectively up to:
QVHZO = 45 l/min
QVKZOR = 90 l/min
Max pressure = 210 bar
