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 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, and the air pressure acts above the diaphragm 2, opening the supply valve core 4 connected to the diaphragm 2 and closing the exhaust valve core 3, generating output pressure. This output pressure is fed back to the control circuit 8 via 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.

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 programmable 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. Less affected by temperature changes. DKZOR-A-171-S5/18

ATOS proportional valve selection basis: 1. Selecting a proportional valve based on pipeline parameters: Nominal diameter (DN) and connection type

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.

2) For connection type, generally, flange connections should be selected for DN > 50, while for DN ≤ 50, the user can choose freely according to their needs.

2. Selecting a solenoid valve based on fluid parameters: Material and temperature group

1) Corrosive fluids: Corrosion-resistant proportional directional valves and all-stainless steel valves are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.

2) High-temperature fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves should be chosen.

3) Fluid state: Valves can be gaseous, liquid, or mixed, especially for diameters greater than DN 25, which must be clearly distinguished.

4) Fluid viscosity: Generally, any choice is acceptable below 50 cSt; if it exceeds this value, a high-viscosity solenoid valve should be selected. ATOS proportional valves

Flow control can be divided into two types:

One is on-off control: either fully open or fully closed, the flow rate 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 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 throttling control of flow rate through electrical control (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 pre-stage control circuit.
