Troubleshooting for ATOS Solenoid Valves
$283.35
DHI-0631/2/WP-X When the magnet coil of the ATOS solenoid valve is energized, the valve body is attracted to a specific direction. By controlling the movement of the valve body, different drain ports are opened or closed. The inlet port 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. In this way, controlling the current to the electromagnet controls the mechanical movement.

ATOS Solenoid Valve Daily Troubleshooting
The following should be checked:
(1) If the ATOS solenoid N terminal is loose or the wire is detached, the solenoid valve will not be energized. Tighten the wire.
(2) If the ATOS solenoid valve coil is burnt out, disconnect the solenoid valve wiring and measure with a multimeter. If it is open-circuited, the solenoid valve coil is burnt out. Causes include coil damage due to NJ, resulting in poor insulation and magnetic leakage, causing excessive current in the coil and burnout. Therefore, prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or too few coil turns can also cause the coil to burn out due to insufficient suction.
(3) ATOS solenoid valve stuck. The clearance between the valve sleeve and the valve core of the solenoid valve is very small. When mechanical impurities are introduced or the valve body is rusted, it is easy to get stuck. The fundamental solution is to disassemble the solenoid, remove the N-core and valve core sleeve, and clean them with CCI4 to ensure the valve core moves freely within the sleeve. During disassembly, pay attention to the assembly sequence of each component and the location of external wiring to ensure correct reassembly and wiring. (5) If the pilot valve is blocked by dirt in the pipeline, the pilot valve cannot open normally, and the main valve cannot open in time. The valve body can be disassembled, cleaned, and reassembled to operate normally. (6) In addition, ATOS solenoid valves are generally installed horizontally. If they are installed on the side, the valve may not close tightly, i.e., internal leakage. Side installation should be avoided as much as possible. 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 operation of the magnetic core will cause the flow to pass through the valve body or be cut off, thereby changing the direction of the fluid. The electromagnetic components of a solenoid valve consist of a stationary iron core, a moving iron core, and a coil; the valve body consists of a spool, a sleeve, and a spring base. The solenoid 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 2-way and 2-position 3-way valves.

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. Controlling the valve body's movement opens or closes different drain holes. 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 of automation systems 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.
