Power Supply Requirements for Italian ATOS Proportional Valves: 1) Select AC or DC solenoid valves according to the type of power supply. Generally, AC power is more readily available; 2) Prioritize AC220V or DC24V voltage specifications; 3) Voltage fluctuations are typically +10% to -15% for AC and ±10% for DC. If these fluctuations exceed these limits, voltage stabilization measures must be taken; 4) Select the rated current and power consumption according to the power supply capacity. Note that AC has a higher VA value during startup; if the capacity is insufficient, prioritize AC power.

Differences between ATOS proportional valves and servo valves

There is no strict definition of the difference between ATOS proportional valves and servo valves. As the performance of proportional valves has improved, they have gradually become similar to servo valves, leading to the emergence of proportional-servo valves in recent years.
The main differences between ATOS proportional valves and servo valves are as follows:
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 Servo valves have no dead zone in the neutral position, while proportional valves do. Therefore, their applications differ. Servo valves and servo proportional valves are mainly 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.
2.2 Servo valves have a higher frequency response (response frequency), reaching up to around 200Hz, while proportional valves generally have a maximum frequency of tens of Hz.
2.3 Servo valves have higher requirements for hydraulic fluid, requiring 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. Rated pressure drop differs.
Proportional servo valves offer performance between servo valves and proportional valves.
ATOS proportional directional valves are a type of proportional valve used to control flow rate and direction.
Features of ATOS proportional valves:
1) Enables stepless adjustment of pressure and speed, avoiding the shock phenomenon that occurs when switching normally open on/off pneumatic valves.
2) Enables remote and programmable control.
3) Simplifies the system and significantly reduces the number of components compared to intermittent control.
4) Compared to hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but its response speed is much slower and it is more sensitive to load changes.
5) Low power consumption, low heat generation, and low noise.
6) Does not cause fires and does not pollute the environment. Less affected by temperature changes.
