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. Common types include check valves, safety valves, directional control valves, and speed control valves.

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

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. The causes include: Moisture in the coil leading to poor insulation and magnetic leakage, resulting in excessive current and burnout. Therefore, it's crucial to prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or too few coil turns resulting in insufficient suction can also cause coil burnout. In an emergency, the manual button on the coil can be switched from the normal "0" position to the "1" position to open the valve.

3. Solenoid valve jamming: The clearance between the solenoid valve's spool sleeve 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 lubricating oil, jamming can easily occur. A possible solution is to insert a steel wire through the small hole at the head to spring it 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 oil mist lubricator nozzle is blocked and if there is sufficient lubricating oil.

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

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 Basis:

1. Selecting the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection method

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

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

2. Selecting Solenoid Valves Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel valves 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 when the diameter is greater than DN25, these must be clearly distinguished.

4) Fluid viscosity: Generally, any viscosity 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 Structural Types

1) Nominal pressure: This parameter has the same meaning as other general-purpose valves and is 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 valve 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 voltage specifications are preferred for ease of use.

5. Selection Based on Continuous Operating Time: Normally Closed, Normally Open, or Continuously Powered

1) When the solenoid valve needs to be open for a long time, and the duration 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 powered type should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, Check Valve, Manual Operation, Water-resistant Fog, Water Spray, Submersible.
