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.

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,

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
