ATOS solenoid valves utilize a combination of direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, energizing the valve causes the electromagnetic force to lift the pilot valve and the main valve closing element sequentially, opening the valve. When the inlet and outlet reach the starting pressure difference, energizing the valve causes the electromagnetic force to actuate the pilot valve, increasing the pressure in the lower chamber of the main valve and decreasing the pressure in the upper chamber, thus using the pressure difference to push the main valve open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.

Main Classifications of ATOS Solenoid Valves:

1. ATOS solenoid valves are classified into three main categories based on their operating principle:

1) Direct-acting Solenoid Valves:

ATOS Solenoid Valve Principle: When energized, the electromagnetic coil generates electromagnetic force to lift the closing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing element onto the valve seat, closing the valve.

ATOS Solenoid Valve Characteristics: It can operate normally under vacuum, negative pressure, and zero pressure, but the nominal diameter generally does not exceed 25mm.

2) Step-by-Step Direct-acting Solenoid Valves:

ATOS Solenoid Valve Principle: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, upon energization, the electromagnetic force directly lifts the pilot valve and the main valve closing element sequentially upwards, opening the valve. When the inlet and outlet reach the starting pressure difference, upon energization, the electromagnetic force actuates the pilot valve, causing the pressure in the lower chamber of the main valve to rise and the pressure in the upper chamber to fall. This pressure difference pushes the main valve upwards. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.

ATOS solenoid valve characteristics: Reliable operation even at zero pressure difference, vacuum, or high pressure, but requires higher power and must be installed horizontally.

3) Pilot-operated solenoid valve:

ATOS solenoid valve principle: When energized, the electromagnetic force opens the pilot orifice, causing the pressure in the upper chamber to drop rapidly, creating a pressure difference around the closing element (higher at the bottom and lower at the top). The fluid pressure pushes the closing element upwards, opening the valve. When de-energized, the spring force closes the pilot orifice, and the inlet pressure quickly creates a pressure difference around the closing element through the bypass orifice, causing the fluid pressure to push the closing element downwards, closing the valve.

ATOS solenoid valve characteristics: Higher upper limit of fluid pressure range; can be installed arbitrarily (customization required), but must meet fluid pressure difference conditions.

2. ATOS solenoid valves are categorized into six subcategories based on differences in valve structure, materials, and operating principles: direct-acting diaphragm structure, step-by-step direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-by-step direct-acting piston structure, and pilot-operated piston structure.

3. ATOS solenoid valves are also classified by function: water solenoid valves, steam solenoid valves, refrigeration solenoid valves, cryogenic solenoid valves, gas solenoid valves, fire-fighting solenoid valves, ammonia solenoid valves, gas solenoid valves, liquid solenoid valves, miniature solenoid valves, pulse solenoid valves, hydraulic solenoid valves, normally open solenoid valves, oil solenoid valves, DC solenoid valves, high-pressure solenoid valves, and explosion-proof solenoid valves.

ATOS Solenoid Valve Selection Considerations:

ATOS Solenoid Valve Selection Criteria:

ATOS solenoid valve selection 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: Principle and Structure

1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by 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. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.

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

5. Selecting 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, normally open valves cannot be selected; a continuously energized type should be chosen. 6. Select auxiliary functions according to environmental requirements: explosion-proof, check valve, manual operation, waterproof mist, water spray, submersible.
