Common Faults of Italian Atos Solenoid Valves

If a solenoid valve does not operate, troubleshoot from the following aspects:

(1) Loose or detached solenoid N-connection; the solenoid valve will not receive power. Tighten the wire.

(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, 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 coil burnout.

(3) Solenoid valve stuck. 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 become 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 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. (5) If the pilot valve is blocked by dirt in the pipeline, the pilot valve cannot open properly, and the main valve cannot open in time. The valve body can be disassembled, cleaned, and reassembled to operate normally. (6) In addition, solenoid valves are generally installed horizontally. If they are installed on the side, it may cause the valve to not close properly, i.e., internal leakage. Side installation should be avoided as much as possible.
