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. The following troubleshooting steps should be taken:

1. Loose or detached 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. Causes include 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 the coil to burn out. 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 Jammed: The clearance between the solenoid valve's spool sleeve and valve core is very small (less than 0.008mm), and it is usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubricating oil, it is easy to jam. A temporary fix 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 there is sufficient lubricating oil.

4. Air Leakage: Air leakage will cause insufficient air pressure, making it difficult for the forced valve to open and close. This is caused by damaged sealing gaskets or worn spool sleeves, resulting in air leakage between several cavities. When troubleshooting a solenoid valve malfunction in a switching system, choose an appropriate time to address the issue while the valve is de-energized. If the problem cannot be resolved within a single switching interval, pause the switching system and address it at a later time. ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control in automation systems. 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. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.

ATOS Solenoid Valve 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 inner diameter of the pipeline or flow requirements.

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

2. Selection of 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 for diameters greater than DN25, which must be clearly distinguished;

4) Fluid viscosity: Generally, any viscosity can be selected below 50 cSt. If the viscosity exceeds this value, a high-viscosity solenoid valve should be selected. ATOS solenoid valves in stock
