Principle of Italian ATOS Solenoid Valves: When energized, electromagnetic force opens the pilot orifice, causing a rapid drop in pressure in the upper chamber. This creates a pressure differential around the closing element, with higher pressure at the bottom and lower pressure at the top. The fluid pressure pushes the closing element upwards, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly creates a pressure differential around the closing element through the bypass orifice, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downwards, closing the valve.

Selection Criteria for Italian ATOS Solenoid Valves:

1. Select the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection method.

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

2) For connection methods, generally, >DN50 requires a flange connection; ≤DN50 can be freely selected according to user needs.

2. Selection of Solenoid Valves Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid 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 are preferred;

3) Fluid state: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN25, which must be clearly distinguished;

4) Fluid viscosity: Generally, any choice is acceptable below 50 cSt. If this value is exceeded, a high-viscosity solenoid valve should be selected.

The Italian ATOS solenoid valve is an electromagnetically controlled industrial device, a fundamental component of automation for controlling fluids. It is an actuator, not limited to hydraulic or pneumatic systems. It is 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 accuracy and flexibility. There are many types of solenoid valves, each playing a different role in a control system. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.
