ATOS Digital Proportional Pressure Reducing Valve RZGA Series

ATOS Digital Proportional Pressure Reducing Valve RZGA Series
RZGO-R , RZGO-REB, RZGO-RES
Sliding valve type direct acting digital proportional pressure reducing valve with integrated pressure sensor for pressure closed-loop control.
There are different types of valves to choose from:
R-type, without integrated amplifier, compared to split type amplifier
Used in conjunction with E-BM-RES, see technical sample GS203
REB type, with basic integrated digital amplifier, analog reference signal and USB interface for software function parameter setting.
RES type, equipped with a fully functional integrated digital amplifier and bus communication interface, used for setting functional parameters, reference signals, and real-time fault diagnosis.
The integrated digital electronic amplifier adjusts the hydraulic pressure of the valve based on the reference signal, with pre adjustment at the factory to ensure interchangeability between valves.

Note: The above performance parameters are obtained in conjunction with Atos electronic amplifiers, see section.
(1) A small pressure value will increase the pressure on the T side
(2) The response time is the average of multiple measurements; The pressure will vary with the change of input signal, influenced by the rigidity of the hydraulic circuit: the better the rigidity of the circuit, the better the dynamic response of the valve, as shown in Section 8.
