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 ordinary 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/proportional servo valves have performance between servo valves and proportional valves.

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

ATOS Proportional Valve Extended Information---Automatic control of electro-proportional valves can be divided into intermittent control and continuous control. Intermittent control is on-off control. Pneumatic control systems use on-off (ON-OFF) directional valves with low operating frequencies to control the opening and closing of the air path. Pressure reducing valves regulate the required pressure, and throttle valves regulate the required flow rate. This traditional pneumatic control system requires multiple pressure reducing valves, throttle valves, and directional valves to achieve multiple output forces and multiple movement speeds. This not only requires more components, increases cost, and complicates the system, but also requires many components to be manually adjusted in advance. Electro-proportional valve control is a type of continuous control, characterized by the output changing with the input, and a certain proportional relationship exists between the output and input. Proportional control is divided into open-loop control and closed-loop control.

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.
