Proportional reducing valves type RZGO-TERS, AERS, 3-way direct operated, with integral or remote pressure transducer, ISO 4401 size 06 RZGO are 3-way proportional pressure reducing valves, direct 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. Valve body Proportional solenoid Spool Integral pressure transducer Integral electronics Main connector Communication connector Screw for air bleeding They are available in different executions: • -TERS with integral pressure transducer ‫ܬ‬ plus digital electronics ‫ ܭ‬preset in closed loop, featuring improved static and dynamic performances. • -AERS as -TERS but without integral pressure transducer (predisposed for connection of remote pressure transducer). MODEL CODE The reduced pressure is controlled by the spool ‫ ,ܩ‬directly operated by the solenoid ‫.ܨ‬ The integral electronics ensures factory presetting, fine functionality plus valve-tovalve interchangeability and simplified wiring and installation. * Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Proportional pressure reducing valve size 06 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) Communication interfaces: PS = Serial BC = CANopen BP = PROFIBUS-DP Electronics options, see section ‫:ݜ‬ I 010 = regulation on port P, discharge in T Following communication interfaces ‫ ܮ‬are available: • -PS, Serial communication interface for configuration, monitoring and firmware updating trough Atos PC 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. Series number The electronic main connector ‫ ܭ‬is 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. = current reference input and monitor (4 ÷ 20 mA) signals Pressure range: 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. Mounting surface: ISO 4401 size 06. Max flow: 12 l/min. Max pressure: 210 bar.
