ATOS solenoid valve DHI-0713-X 110/50/60AC, available in Shanghai.

Common ATOS solenoid valve malfunctions include the solenoid valve not operating. Troubleshooting should be done from the following aspects:

(1) Loose or detached solenoid N terminal. The solenoid valve will not receive power. Tighten the terminal.

(2) Burned-out solenoid coil. Disconnect the solenoid valve wiring and measure with a multimeter. If an open circuit is detected, the solenoid coil is burnt out. This can be caused by the coil being subjected to NJ (non-electric shock), resulting in poor insulation and magnetic leakage, leading to 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 burnout.

(3) Solenoid valve jamming. The clearance between the valve sleeve and valve core of the solenoid valve is very small. When mechanical impurities are introduced or the valve body is rusted, it can easily jam. The fundamental solution is to disassemble the solenoid valve, remove the N 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 position of the external wiring to ensure correct reassembly and wiring. (5) If it is a pilot-operated solenoid valve, check if the differential pressure in the pipeline is too small. If the differential pressure is too small, the solenoid valve will not work properly. In this case, a direct-acting solenoid valve should be selected. If the differential pressure is too large, far exceeding the design value of the solenoid valve, it will also not work properly. In this case, a high-performance solenoid valve should be used.

(6) If dirt in the pipeline blocks the small hole of the pilot valve, the pilot valve cannot open properly, and the main valve cannot open in time. The valve body can be disassembled, the dirt cleaned, and reassembled to work properly.

(7) In addition, solenoid valves are generally installed horizontally. If they are side-mounted, it may cause the valve to not close tightly, i.e., internal leakage. Side-mounting should be avoided as much as possible. ATOS solenoid valves contain a sealed chamber with through-holes at different locations, each connecting to a different oil pipe. Inside the chamber is a piston, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side, opening or closing different drain holes by controlling the valve body's movement. 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. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.

ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control in automation. 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.
