Structural Principle of Italian ATOS Proportional Directional Valves When the input signal 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 input signal. Because there is no nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.

Features of the Italian ATOS proportional directional valve:

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

2) Enables remote 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 hydraulic systems, and it is more sensitive to load changes.

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

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

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

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

Extended Information---Automatic control of electric proportional valves can be divided into intermittent control and continuous control. Intermittent control is on/off control. Pneumatic control systems use on/off directional valves with low operating frequency to control the opening and closing of the air path. Pressure reducing valves are used to regulate the required pressure, and throttle valves are used to 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 an output that changes proportionally to the input, with a certain proportional relationship between the two. Proportional control can be divided into open-loop control and closed-loop control.
