Proportional pressure valves AGMZO-AES
7Pages

Proportional relief valves type AGMZO-AES two stage, without integral pressure transducer, ISO 6264 size 10, 20 and 32 AGMZO are poppet type proportional pressure relief valves, pilot operated without integral 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: • -A, without integral pressure transducer. • -AE, -AES, as -A plus analogue (AE) or digital (AES) integral electronics ‫.ܫ‬ Main poppet Mechanical pilot relief valve Integral electronics The pilot relief valve ቤ with manual adjustment is installed to limit the max pressure value. Main connector -BC or -BP communication connector The integral electronics ብ ensures factory presetting, fine functionality plus valve-tovalve interchangeability and simplified wiring and installation. -PS communication connector (1) -EH Communication connector (input) -EH Communication connector (output) G1/4” pipe connection for external drain MODEL CODE * Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Proportional pressure relief valve A = without integral transducer AE = as A plus integral electronics AES = as A plus integral digital electronics Series number Hydraulic options: E = external pilot Y = external drain (only pipe connection G1/4”) (1) Communication interfaces (only for AES): PS BC BP EH The piloting pressure to the poppet ቢ is modulated by a proportional relief valve type RZMO ባ, see table F007. Pilot relief valve type RZMO = Serial (1) = CANopen = PROFIBUS DP = EtherCAT Pressure range: 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 input (4÷20 mA) Q = enable signal Electronics options for -AES execution, see section ‫:ݟ‬ Q = enable signal Z = adds double power supply, enable and fault signals (12 pin connector) The electronic main connector ቦ 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 ቧ, ቨ , ቩ , ቪ are available for the -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. The coils are fully plastic encapsulated with insulation class H. Mounting surface: ISO 6264 size 10, 20 and 32. Max flow: 200, 400, 600 l/min Max pressure: 350 bar.

GENERAL NOTES AGMZO proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC 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 systems and...

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)...
