Proportional reducing valves type AGRCZO-TERS, AERS
two stages, with integral or remote pressure transducer, ISO 5781 size 10 and 20
AGRCZO are two-stage normally closed
proportional pressure reducing valves with
integral or remote pressure transducer
wich provide pressure regulation proportional to electronic reference signal.
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:
• -TERS with integral pressure transducer ‫ܫ‬
plus digital electronics ‫ ܬ‬preset in closed
loop, featuring improved static and
dynamic performances.
• -AERS as -TERS but without integral
pressure transducer (predisposed for
connection of remote pressure
transducer).

Main poppet
Pilot relief valve type RZMO
Flow control cartridge

The piloting pressure to the main poppet ‫ܨ‬
is modulated by a proportional pilot pressure relief valve type RZMO ‫ ,ܩ‬see tab. F010.
A modular pressure compensated flow control cartridge ‫ ܪ‬assures constant pilot flow
and therefore high pressure stability.

Pressure range:

Z = double power supply, enable fault and
monitor signals (12 pin connector)

100 = 100 bar
210 = 210 bar
315 = 315 bar
350 = 350 bar

The electronic main connector ‫ ܮ‬is fully
interchangeable for -TERS and -AERS
executions. Standard 7 pin connector is
used for power supply, analog input
reference and monitor signals.
12 pin connector is used option /Z.
Following communication interfaces ‫ ܭ‬are
available:
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating trough Atos PC software
• -BC, CANopen interface
• -BP, PROFIBUS DP interface

Series number

Communication interfaces:

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

= current reference input and monitor
(4 ÷ 20 mA) signals

C = remote pressure transducer with current feedback 4÷20 mA (only for
AERS executions)

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
features.
Surface mounting: ISO 5781 size 10 and 20.
Max flow: 160, 300 l/min respectively
Max pressure: 350 bar.
