Atos Proportional reducing valves RZGO

They are proportional pressure reducing valves, 3-way, pilot operated, available in two different executions:
- R subplate mounting;
- H or K modular mounting.

They operate in association with electronic drivers, see table 2 which supply the pro- portional valve with proper current signal 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 ④.

The reduced pressure is controlled by the spool ① piloted by the proportional pilot relief valve ②. The intermediate compensated flow cont rol cartridge ③
assures constant pilot flow and therefore high pressure stability.

The integral electronics ④ ensures factory presetting, fine functionality plus valve-to- valve interchangeability and simplified wiring and installation.

The electronic main connector ⑤ 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 for option /Z (AES). Following communication interfaces ⑥ ⑦ ⑧ ⑨ are available for the digital -AES
execution:
- PS, Serial communication interface for configuration, monitoring and firmware updating through Atos PC software - always present
- 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.
