Features of ATOS Directional Proportional Valves:

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

2) Enables remote 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 hydraulic systems, and it is more sensitive to load changes.

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

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

Extended Information---Automatic control of electrical 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 frequency to control the opening and closing of the air circuit. The required pressure is regulated by a pressure reducing valve, and the required flow rate is regulated by a throttle valve. 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 continuous control system, characterized by output varying 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.

A. TOS Directional Proportional Structure Principle:

When the input signal increases, the pilot valve 1 of the air supply solenoid valve reverses, while the exhaust solenoid pilot valve 7 is in the reset state. The air supply pressure enters the pilot chamber 5 from the SUP port through valve 1. The pilot chamber pressure rises, and the air pressure acts above the diaphragm 2, causing the air supply valve core 4 connected to the diaphragm 2 to open, and the exhaust valve core 3 to close, 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 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.
