ATOS proportional valves control flow in two ways: On-off control and continuous control. On-off control means the valve is either fully open or fully closed, with the flow rate either at its maximum or minimum, without intermediate states. Examples include common solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. Continuous control allows the valve to open to any desired degree, thus controlling the flow rate. These valves can be manually controlled (e.g., throttle valves) or electrically controlled (e.g., proportional valves and servo valves). Therefore, the purpose of using proportional or servo valves is to achieve flow control through electrical means (and, with structural modifications, pressure control can also be achieved). Since it's flow 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 solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.

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

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

ATOS proportional valve extended information---Automatic control of electric proportional valves can be divided into intermittent control and continuous control. Intermittent control is also known as on/off control. Pneumatic control systems use low-frequency on/off directional valves 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 increases the number of components, raising costs and complicating the system structure, but also requires many components to be manually adjusted in advance. Electro-proportional valve control is a type of continuous control, characterized by output that changes proportionally to input, with a certain proportional relationship between the two. Proportional control can be divided into open-loop and closed-loop control.

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 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.

ATOS Proportional Valve Features

1) It can achieve stepless adjustment of pressure and speed, avoiding the impact phenomenon during switching of normally open on/off valves. 2) Enables remote and program-based 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 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. DHZO-A-073-S3 20
