ATOS Proportional Reducing Valves AGMZO-TERS-PS-10/210/I Reducing Valves Pressure Reducing Valve 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 , which 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 . The piloting pressure to the poppet is modulated by a proportional relief valve type RZMO , see table F007. The pilot relief valve with manual adjustment is installed to limit the max pressure value. The integral electronics ensures factory presetting, fine functionality plus valve-tovalve interchangeability and simplified wiring and installation. The electronic main connector 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 , , , 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 ba |
