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). Main spool Poportional pilot relief valve 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.

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.
