Proportional reducing valves type RZGO-AES, 3-way direct operated, without integral pressure transducer, ISO 4401 size 06 RZGO are 3-way proportional pressure reducing valves, direct operated without integral pressure transducer, which 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 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 ‫.ܫ‬ The reduced pressure is controlled by the spool ‫ ,ܪ‬directly operated by the solenoid ‫.ܩ‬ Valve body Proportional solenoid The integral electronics ‫ ܫ‬ensures factory presetting, fine functionality plus valve-tovalve interchangeability and simplified wiring and installation. Integral electronics Main connector -BC/-BP Communication connector The electronic main connector ‫ ܬ‬is 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 for option /Z (AES). -PS Communication connector (1) -EH Communication connector (input) -EH Communication connector (output) Screw for air bleeding MODEL CODE * Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Proportional pressure reducing valve size 06 A = without integral transducer AE = as A plus integral electronics AES = as A plus integral digital electronics The valves with -BC and -BP interfaces can be integrated into a fieldbus communication network and thus digitally operated by the machine control unit.

GENERAL NOTES RZGO proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive). Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and in the installation notes supplied with relevant components. The electrical signals of the valve (e.g. monitor signals) must not be directly used to activate safety functions, like to switch-ON/OFF the machine’s safety components, as prescribed by the European standards (Safety requirements of fluid technology...

DIGITAL INTEGRAL DRIVERS -AES - OPTIONS Standard driver execution provides on the 7 pin main connector: Power supply - 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers. Reference input signal - analog differential input with 0÷+10 VDC nominal range (pin D, E), proportional to desired coil current (4÷20 mA with cable break detection, ± 10 mA, ± 20 mA or 0÷20 mA software selectable)...
