ATOS Proportional Valve Structure and Principle:

When the input signal to the ATOS proportional valve increases, the pilot valve 1 of the air supply solenoid valve reverses, while the exhaust solenoid pilot valve 7 remains in the reset state. The air supply pressure then enters the pilot chamber 5 from the SUP port through valve 1. The pressure in the pilot chamber rises, and the air pressure acts above the diaphragm 2. This opens the air supply valve core 4 connected to the diaphragm 2, while the exhaust valve core 3 closes, generating output pressure. This output pressure is fed back to the control circuit 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 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 have performance between servo valves and proportional valves.

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

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 can be divided into open-loop control and closed-loop control.

ATOS proportional valves can control flow in two ways: one is on/off control: either fully open or fully closed, with the flow rate 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 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 valves or servo valves is to achieve throttling control of flow rate electronically (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.
