Proportional reducing valves type AGRCZO-AES
two stages, normally closed, without integral pressure transducer, ISO 5781 size 10 and 20
AGRCZO are two-stage normally closed
proportional pressure reducing valves
without integral pressure transducer, which
provide pressure regulation proportional to
electronic reference signal.

9

They operate in association with electronic
drivers, see table ‫ ݘ‬which supply the proportional valve with proper current signal to
align valve regulation to the reference
signal supplied to the electronic driver.

They are available in different executions:
• -A, without integral pressure transducer.
• -AE, -AES, as -A plus analogue (AE) or
digital (AES) integral electronics ቦ.

The piloting pressure to the poppet ‫ ܨ‬is
modulated by a proportional pressure relief
valve type RZMO ‫ ,ܩ‬see tab. F007.
A modular pressure compensated flow control cartridge ‫ ܪ‬assures constant pilot flow
and therefore high pressure stability.

The integral electronics ቦ ensures factory
presetting, fine functionality plus valve-tovalve interchangeability and simplified
wiring and installation.

Coil voltage (only for -A execution) see
section ‫:ݛ‬
- = standard coil for 24VDC Atos drivers
6 = optional coil for 12VDC Atos drivers
18 = optional coil for low current drivers
Electronics options for -AE execution,
see section ‫:ݝ‬
I = current reference (4÷20 mA)
Q = enable signal

50 = 32 bar
100 = 100 bar
210 = 210 bar
315 = 315 bar
350 = 350 bar

The electronic main connector ቧ is fully
interchangeable 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 option /Z (AES).
Following communication interfaces ቨ,
ቩ, ቪ, ቫ 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.

Electronics options for -AES execution,
see section ‫:ݟ‬
Q = enable signal
Z = adds double power supply, enable
and fault signals (12 pin connector)

Size: 10, 20

The coils are fully plastic encapsulated
with insulation class H.
Surface mounting: ISO 5781 size 10 and 20.
Max flow: 160, 300 l/min respectively
Max pressure: 350 bar.

(1) Serial communication interface always present, also for -BC, -BP and -EH options
