Proportional relief valves type AGMZO-TERS, AERS two stage, with integral or remote pressure transducer, ISO 6264 size 10, 20 and 32 AGMZO are two stage poppet type proportional pressure relief valves, with integral or remote pressure transducer, wich 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. Main poppet Pilot relief valve type RZMO Mechanical pilot relief valve Integral pressure transducer Integral electronics Communication connector Main connector G1/4” pipe connection for external drain MODEL CODE * Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Proportional relief valve 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) Series number Communication interfaces: PS = Serial BC = CANopen BP = PROFIBUS-DP Hydraulic options, see section ‫:ݜ‬ E = external pilot Y = external drain (only pipe connection G1/4”) (1) Electronics options, see section ‫:ݜ‬ I = current reference input and monitor (4 ÷ 20 mA) signals Z = double power supply, enable fault and monitor signals (12 pin connector) C = remote pressure transducer with current feedback 4÷20 mA (only for AERS executions) 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). The piloting pressure to the main poppet ‫ܨ‬ is modulated by a proportional pilot relief valve type RZMO ‫ ,ܩ‬see table F010. The mechanical relief valve ‫ ܪ‬with 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 ‫ 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 PL software • -BC, CANopen interface • -BP, PROFIBUS DP 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 (insulation class H), and the valves have antivibration, antishock and weather-proof features. . Surface mounting: ISO 6264 size 10, 20 and 32.
