ATOS/Italian Atos

ATOS proportional valves control flow in two ways: On-off control and continuous control. On-off control means the valve is either fully open or fully closed, with the flow rate either at its maximum or minimum, without intermediate states. Examples include common solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. Continuous control allows the valve to open to any desired degree, thus controlling the flow rate. These valves can be manually controlled (e.g., throttle valves) or electrically controlled (e.g., proportional valves and servo valves). Therefore, the purpose of using proportional or servo valves is to achieve flow control through electrical means (pressure control can also be achieved with structural modifications). Since it's throttling control, there is inevitably 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 upstream control circuit.

ATOS proportional valves offer performance between servo valves and proportional valves.

ATOS proportional valves are a type of proportional valve used to control flow rate and direction.

Extended Information---Automatic control of electrical proportional valves can be divided into intermittent control and continuous control. Intermittent control, also known as on/off control, uses low-frequency on/off directional valves in pneumatic control systems to control the flow of air. Pressure reducing valves regulate the required pressure, and throttle valves regulate the required flow rate. To achieve multiple output forces and speeds, this traditional pneumatic control system requires multiple pressure reducing valves, throttle valves, and directional valves. This not only increases the number of components, raising costs and complicating the system, but also necessitates manual adjustment of many components beforehand. Electro-proportional valve control, on the other hand, is a continuous control system. Its characteristic is that the output changes with the input, and there is a proportional relationship between the output and input. Proportional control can be open-loop or closed-loop.

ATOS Proportional Valve Structure and Principle

When the input signal to the ATOS proportional valve increases, the pilot valve 1 of the supply solenoid valve switches, while the exhaust solenoid pilot valve 7 remains in the reset state. The supply pressure then enters the pilot chamber 5 from the SUP port through valve 1. The pilot chamber pressure rises, and this pressure acts on the diaphragm 2, opening the supply valve core 4 connected to diaphragm 2 and closing the exhaust valve core 3, generating output pressure. This output pressure is fed back to the control loop 8 via pressure sensor 6. Here, a rapid comparison and correction is performed with the target value until the output pressure is proportional to the input signal, thus demonstrating that the output pressure changes proportionally to the change in the input signal. Because there is no nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.

ATOS Proportional Valve Features

1) Enables stepless adjustment of pressure and speed, avoiding the impact phenomenon during switching of normally open on/off valves.

2) Enables remote control and program control.

3) Compared to intermittent control, the system is simplified, and the number of components is greatly reduced. 4) Compared to hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but its response speed is much slower than that of a hydraulic system, and it is more sensitive to load changes.

5) It uses less power, generates less heat, and produces less noise.

6) It will not cause a fire and will not pollute the environment. It is less affected by temperature changes.
