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.

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 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 output changing with input, and a certain proportional relationship exists between the output and input. Proportional control is divided into open-loop control 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 this pressure acts 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 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 Valve Features

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

2) Enables remote control and program control.

3) Compared to intermittent control, the system is simplified, and the number of components is greatly reduced. 4) Compared to hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but its response speed is much slower than that of a hydraulic system, 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.

ATOS proportional valves can control flow in two ways: one is on/off control: either fully open or fully closed, the flow is either at its maximum or minimum, with no intermediate state, such as ordinary solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. The other is continuous control: the valve port can be opened 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.

ATOS Proportional Valve Structure and Principle:

When the input signal increases, the pilot valve 1 of the air supply solenoid valve switches, while the solenoid pilot valve 7 of the exhaust solenoid valve is in the reset state. The air supply pressure enters the pilot chamber 5 from the SUP port through valve 1. The pressure in the pilot chamber rises, and the air pressure acts on the diaphragm 2. The air supply valve core 4 connected to the diaphragm 2 then opens, and the exhaust valve core 3 closes, generating output pressure. This output pressure is fed back to the control loop 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 obtaining the condition that the output pressure changes proportionally to the change in the input signal. Because it lacks a nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.
