Italian ATOS solenoid valves are mostly used for open-loop control; secondly, proportional valves offer a wider variety, including proportional pressure and flow control valves, providing more flexible control than servo valves. Internally, servo valves typically have zero overload, while proportional valves have a certain dead zone, resulting in lower control accuracy and slower response. However, looking at development trends, especially in proportional flow control valves and servo valves, the performance difference between the two is gradually narrowing. Furthermore, proportional valves are significantly cheaper than servo valves and have stronger resistance to contamination.

ATOS Solenoid Valve Selection Criteria:
The selection of ATOS solenoid valves should first follow four principles in order: safety, reliability, applicability, and economy. Secondly, it should be based on six aspects of the on-site operating conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements). ATOS Solenoid Valve Selection Criteria:
1. Selection of Solenoid Valves Based on Pipeline Parameters: Nominal Diameter (DN), Connection Type
1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.
2) Connection type: Generally, for DN >50, a flange connection should be selected; for DN ≤50, the connection type can be freely selected according to user needs.
2. Selection of Solenoid Valves Based on Fluid Parameters: Material, Temperature Group
1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel 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: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN25, it is essential to distinguish between these states.
4) Fluid Viscosity: Generally, any fluid can be selected below 50 cSt; if it exceeds this value, a high-viscosity solenoid valve should be selected. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principles and Structural Types
1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by the nominal pressure of the pipeline.
Performance Requirements for Italian ATOS Solenoid Valves:
1. Reversing Performance
Under specified operating conditions, whether the solenoid valve can reliably reverse direction after being energized and reliably reset after being de-energized.
2. Pressure Loss
The pressure loss of a solenoid directional valve consists of flow loss and throttling loss generated when the fluid flows through the valve port.
3. Internal Leakage
The internal leakage of a solenoid directional valve refers to the leakage from the high-pressure chamber to the low-pressure chamber under specified operating conditions and in various operating positions.
4. Reversing and Reset Time
The time required from energizing the solenoid to the termination of valve spool reversal; the reset time is the time required from de-energizing the solenoid to the valve spool returning to its initial position. 5. Switching Frequency
The maximum number of switching operations allowed per unit time.
6. Service Life
The solenoid valve is considered to be in service until its main components are damaged, preventing it from performing normal switching and reset actions, or until its main performance indicators deteriorate significantly beyond the specified number of switching operations. [1]

Italian ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. They are 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 precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.
