Proportional reducing valves type RZGO-TERS, -AERS, 3-way
pilot operated, with integral or remote pressure transducer, ISO 4401 size 06
RZGO are 3-way proportional pressure
reducing valves, pilot operated with integral or remote pressure transducer, which
provide pressure regulation proportional
to electronic reference signal.
They operate in association with electronic drivers, see section ‫ ,ݘ‬which supply
the proportional valve with proper current
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).

Flow control cartridge

The reduced pressure is controlled by the
main spool ‫ ܨ‬piloted by the proportional
pilot relief valve ‫ .ܩ‬The intermediate
compensated flow control cartridge ‫ܪ‬
assures constant pilot flow and therefore
high pressure stability.

TERS = with integral digital electronics
and pressure transducer
AERS = as TERS but predisposed for
connection of remote pressure
transducer (to be ordered
separately, see tab. G460)

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 for 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:
PS = Serial
BC = CANopen
BP = PROFIBUS DP
Electronics options, see section ‫:ݜ‬
Configuration:

The valves with -BC and -BP interfaces can
be integrated into a fieldbus communication
network and thus digitally operated by the
machine control unit.

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

The coils are fully plastic encapsulated
(insulation class H), and the valves have
antivibration, antishock and weather-proof
features.

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

Mounting surface: ISO 4401 size 06, 10.
Max flow: 100 l/min.
Max pressure: 350 bar.

033 = regulation on port A, pressure from P, discharge in T
Pressure range:
100 = 100 bar
210 = 210 bar
315 = 315 bar
350 = 350 bar

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