ATOS/Italian Atos

ATOS proportional directional valves control flow in two ways: One is on/off control: either fully open or fully closed, with flow either at its maximum or minimum, without intermediate states, such as ordinary solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. The other is continuous control: the valve port can open to any degree as needed, thereby controlling the flow rate. These valves can be manually controlled, such as throttle valves, or electrically controlled, such as proportional valves and servo valves. Therefore, the purpose of using proportional or servo valves is to achieve flow throttling control electrically (of course, pressure control can also be achieved through structural modifications). Since it is 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 pre-stage control circuit.

Features of ATOS proportional directional valves:

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

2) Enables remote and program control.

3) Compared to intermittent control, the system is simplified, with a significant reduction in components.

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 produces less noise.

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

ATOS Proportional Direction Structure Principle:

When the input signal increases, the pilot valve 1 of the air supply solenoid valve switches, while the exhaust solenoid pilot valve 7 is in the reset state. The air supply pressure enters the pilot chamber 5 from the SUP port through valve 1. The pilot chamber pressure rises, and the air pressure acts on the diaphragm 2. The air supply valve core 4 connected to the diaphragm 2 then opens, and the exhaust valve core 3 closes, generating output pressure. This output pressure is fed back to the control loop 8 through the 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 obtaining the condition that the output pressure changes proportionally to the change in the input signal. Because it lacks a nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.
