ATOS proportional servo valves offer performance between servo valves and proportional valves.

ATOS 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 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, increasing costs and complicating the system, but also necessitates manual adjustment of many components beforehand. Electro-proportional valve control is a continuous control method, characterized by output varying with input, exhibiting a proportional relationship between the two. Proportional control can be open-loop or closed-loop.

ATOS Proportional Valve Structure and Principle:

When the input signal increases, the pilot valve 1 of the supply solenoid valve reverses, 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, acting 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 with the target value is performed 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.

ATOS proportional valve features:

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

2) Enables remote and program control.

3) Simplifies the system and greatly reduces the number of components compared to intermittent control.

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

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

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

ATOS proportional valves can control flow in two ways: On/off control: either fully open or fully closed, with flow either at maximum or minimum, without intermediate states, such as ordinary solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. Continuous control: the valve can open to any degree as needed, thereby controlling the flow rate. These valves include manually controlled ones, such as throttle valves, and electrically controlled ones, such as proportional valves and servo valves. Therefore, the purpose of using proportional valves or servo valves is to achieve flow throttling control electronically (of course, pressure control can also be achieved through structural modifications). Since it is throttling control, there will inevitably be 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.
