ATOS/Italian Atos

ATOS proportional valves are precise in operation, featuring high accuracy, high response, and high reliability electronic closed-loop feedback, and have a wide range of applications. ISO cartridge valves can function as either on/off valves or proportional valves, depending primarily on the valve's cap. ISO cartridge valves can be used with internal sensors in the control valve on the cap. All proportional valves can be used with external actuators or the necessary electronic components for the entire system. Currently, almost all proportional valves can be connected to digital actuators. A computer can configure and manage digital actuators and proportional valves via a USB cable connection.

ATOS proportional valves control flow in two ways: On/off control: either fully open or fully closed, with flow either at maximum or minimum, without intermediate states, such as ordinary solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. Continuous control: the valve can open to any degree as needed, thereby controlling the flow rate. These valves include manually controlled ones, such as throttle valves, and electrically controlled ones, such as proportional valves and servo valves. Therefore, the purpose of using proportional valves or servo valves is to achieve flow throttling control electronically (of course, pressure control can also be achieved through structural modifications). Since it's throttling control, there will inevitably be energy loss. Servo valves differ from other valves in that their energy loss is greater because they require a certain flow rate to maintain the operation of the pre-stage control circuit.

Differences between ATOS proportional valves and servo valves:

Mainly in the following aspects:

1. Different drive devices. The drive device for proportional valves is a proportional electromagnet; the drive device for servo valves is a force motor or torque motor;

2. Different performance parameters. 2.1 Due to differences in characteristics such as hysteresis, dead zone, bandwidth, and filtration accuracy, ATOS servo valves and servo proportional valves are primarily used in closed-loop control systems, while other proportional valve structures are mainly used in open-loop control systems and closed-loop speed control systems.

2.1 ATOS servo valves have no dead zone in the neutral position, while proportional valves do.

2.2 ATOS servo valves have a higher frequency response, reaching up to approximately 200Hz, while proportional valves typically have a maximum frequency of tens of Hz.

2.3 ATOS servo valves have higher requirements for hydraulic fluid, requiring fine filtration to prevent clogging, while proportional valves have lower requirements.

3. Valve core structure and machining precision differ. Proportional valves use a valve core + valve body structure, with the valve body also serving as the valve sleeve. Servo valves and servo proportional valves use a valve core + valve sleeve structure.

4. Neutral position functions differ. Proportional directional valves have neutral position functions similar to ordinary directional valves, while servo valves only have an O-type neutral position function (E-type for Rexroth products).

5. The rated pressure drop of the valves differs.

The performance of the ATOS proportional servo valve falls between that of a servo valve and a proportional valve.

The ATOS proportional directional valve is a type of proportional valve used to control flow rate and direction.
