ATOS Solenoid Directional Valve, ATOS Pressure Reducing Valve, ATOS Safety Valve, ATOS Control Valve

ATOS proportional valves 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 straight-through valves, solenoid directional valves, and electro-hydraulic directional valves. 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 upstream control circuit.

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 also known as on-off control. Pneumatic control systems use on-off (ON-OFF) directional valves with low operating frequencies to control the flow of air. 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, 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 is divided into open-loop control and closed-loop control.

Overview of Italian ATOS Proportional Valves:

Italian 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 valves 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 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 pre-stage control circuit.

Features of ATOS proportional valves:

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 its response speed is much slower than that of 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. ATOS proportional valve stock models are as follows:
