ATOS solenoid valves consist of an electromagnetic coil and a magnetic core, and are valve bodies containing one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes fluid to flow through the valve body or be cut off, thereby changing the fluid direction. The electromagnetic components of a solenoid valve consist of a fixed iron core, a moving iron core, and a coil; the valve body consists of a spool, a spool sleeve, and a spring base. The electromagnetic coil is directly mounted on the valve body, which is enclosed in a sealing tube, forming a simple and compact assembly. Commonly used solenoid valves in production include 2-position 3-way, 2-position 4-way, and 2-position 5-way valves. Here, let's first explain the meaning of "2-position": for a solenoid valve, it means energized and de-energized; for the valve it controls, it means open and closed.

A malfunction in an ATOS solenoid valve will directly affect the operation of the switching and regulating valves. Common malfunctions include the solenoid valve not operating. Troubleshooting should focus on the following:

1. Loose or disconnected solenoid valve wiring: The solenoid valve will not receive power. Tighten the wiring.

2. Burned-out solenoid valve coil: Disconnect the solenoid valve wiring and use a multimeter to measure. If an open circuit is detected, the solenoid valve coil is burnt out. This can be caused by moisture in the coil, leading to poor insulation and magnetic leakage, resulting in excessive current and burnout. Therefore, prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or insufficient coil turns can also cause coil burnout. In an emergency, switch the manual button on the coil from the normal "0" position to the "1" position to open the valve.

3. Solenoid valve stuck: The clearance between the solenoid valve's spool and valve core is very small (less than 0.008mm), and they are usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubrication, the valve can easily become stuck. The first method is to insert a steel wire through the small hole at the head to make it spring back. The fundamental solution is to disassemble the solenoid valve, remove the valve core and valve core sleeve, and clean them with CCI4 to ensure the valve core moves freely within the valve sleeve. During disassembly, pay attention to the assembly sequence of each component and the location of external wiring to ensure correct reassembly and wiring. Also check if the lubricator spray hole is blocked and if the lubricating oil is sufficient.

4. Air Leakage: Air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve. This is caused by damaged gaskets or worn spool valves, resulting in air leakage between several cavities. When troubleshooting a solenoid valve malfunction in a switching system, choose an appropriate time to handle it when the solenoid valve is de-energized. If the problem cannot be resolved within a single switching interval, pause the switching system and handle it at a later time.

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 accuracy and flexibility. There are many types of solenoid valves, each playing a different role in a control system. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.

ATOS Solenoid Valves

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 Valves

Selection Criteria:

1. Select 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 requirements.

2) For connection type, generally, >DN50 requires a flange connection; ≤DN50 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; For 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 fluid can be selected below 50 cSt. If this value is exceeded, a high-viscosity solenoid valve should be selected. 3.

Selecting Solenoid Valves Based on Pressure Parameters: Principle 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.

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 valves can all be selected.

4. Electrical Selection: AC220V or DC24V should be prioritized for convenience. 5. Select 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 continuously energized type cannot be selected and should be chosen.

6. Select auxiliary functions based on environmental requirements: Explosion-proof, check valve, manual operation, waterproof mist, water spray, submersible. ATOS solenoid valve
