Description
Proportional reducing valves
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,which supply the proportional valve with proper current signal toalign valve regulation to the reference
signal supplied to the electronic driver.
 
Proportional reducing valves type RZGO-AES, HZGO-A, KZGO-A
pilot operated, without integral pressure transducer, subplate or modular mounting, ISO 4401 size 06, 10
 
 
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.
Reduced pressure on port A for valves 033 and on port P1 for valves 031.
