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. 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.

ATOS Solenoid Valves are mainly classified as follows:

1. Based on their operating principle, solenoid valves are divided into three main categories:

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 back onto the valve seat, closing the valve. Features: Operates 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 valve:

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, 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 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 features: Reliable operation even under 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, 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 lower pressure at the top and higher pressure at the bottom. The fluid pressure pushes the closing element upward, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downward, 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 differential conditions.

2. Solenoid valves are divided 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. Solenoid valves are 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, explosion-proof solenoid valves, etc.

ATOS Solenoid Valve Applicability:

1. Media Characteristics

1) Different types of solenoid valves should be selected for gaseous, liquid, or mixed states;

2) Different specifications of products should be used for different media temperatures, otherwise the coil will burn out, the seals will age, and the lifespan will be severely affected;

3) Media viscosity is usually below 50 cSt. If it exceeds this value, a multi-functional solenoid valve should be used when the nominal diameter is greater than 15 mm; a high-viscosity solenoid valve should be used when the nominal diameter is less than 15 mm.

4) When the cleanliness of the medium is not high, a backflush filter valve should be installed before the solenoid valve. For low pressure, a direct-acting diaphragm solenoid valve can be used.

5) If the medium flows in a directional manner and backflow is not allowed, a bidirectional flow valve is required.

6) The medium temperature should be selected within the allowable range of the solenoid valve.
