ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control in automation. 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 accuracy and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common types are check valves, safety valves, directional control valves, and speed control valves.

When selecting ATOS solenoid valves, the primary principles should be safety, reliability, applicability, and economy. Secondly, selection 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. Selecting the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection type

1) Determine the nominal diameter (DN) based on the on-site pipeline inner diameter or flow requirement;

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

2. ATOS solenoid valve selection 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 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 viscosity can be selected below 50 cSt. If this value is exceeded, a high-viscosity solenoid valve should be selected. DHI-0630/2/A-X 24DC 23

3. ATOS Solenoid Valve Selection Based on Pressure Parameters: Principle and Structural Types

1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves and is determined based on the nominal pressure of the pipeline; 2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected; when the minimum working pressure difference is above 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated types can all be selected.

4) Electrical Selection: AC220V or DC24V voltage specifications should be prioritized for convenience.

5) Selection based on continuous working time: Normally closed, normally open, or continuously energized

1) When the solenoid valve needs to be open for a long time, and the continuous time is longer than the closing time, a normally open type should be selected;

2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected;

3) However, for some safety protection applications, such as furnace and kiln flame monitoring, a normally open type cannot be selected; a continuously energized type should be chosen.

6) Selection of auxiliary functions based on environmental requirements: Explosion-proof, check valve, manual operation, waterproof mist, water spray, submersible.
