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 the air pressure acts on the diaphragm 2, causing the supply valve core 4 connected to diaphragm 2 to open, while the exhaust valve core 3 closes, generating output pressure. This output pressure is fed back to the control circuit 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 valves can control flow in two ways: one is on/off control: either fully open or fully closed, the flow rate is either maximum or minimum, with no intermediate state, such as ordinary solenoid straight-through valves, solenoid directional valves, and electro-hydraulic directional valves. Another type 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 control through electrical means (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 upstream control circuit.

ATOS proportional valve features:

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

2) Enables remote and program control.

3) Compared with intermittent control, the system is simplified, and the number of components is greatly reduced.

4) Compared with hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but the response speed is much slower than hydraulic systems, and it is more sensitive to load changes.

5) Low power consumption, low heat generation, and low noise.

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