Main Classifications of ATOS Solenoid Valves:

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

1) Direct-acting Solenoid Valves:

Principle of ATOS Solenoid Valves: 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.

Characteristics of ATOS Solenoid Valves: They can operate normally under vacuum, negative pressure, and zero pressure, but the nominal diameter is generally no more than 25mm.

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

Principle of ATOS Solenoid Valves: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, after 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.

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, creating a lower pressure difference at the top and higher pressure at the bottom. The fluid pressure pushes the closing element downwards, closing the valve.

ATOS solenoid valve features: High 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

Selection Basis

The selection of ATOS solenoid valves should first follow four principles in order: 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. Selection of Solenoid Valve 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 Valve 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 for diameters greater than DN 25, which must be clearly distinguished.

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. ATOS Solenoid Valve Model List:

ATOS solenoid valve working principle:

The ATOS solenoid valve has a sealed chamber with through-holes at different positions, each connecting to a different oil pipe. In the center of the chamber is a piston, and on either side are two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. By controlling the movement of the valve body, different drain holes are opened or closed. The inlet hole is always open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Mechanical movement is controlled by switching the current to the electromagnet on and off.

ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems 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. Common types include check valves, safety valves, directional control valves, and speed control valves.
