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

(1) Loose or detached N-connector of the solenoid valve; the solenoid valve will not be energized. Tighten the wire. (2) If the 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. This can be caused by the coil being subjected to heat, 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 too few coil turns and insufficient suction can also cause the coil to burn out.

(3) If the solenoid valve is stuck, the clearance between the valve sleeve and the valve core 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 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. “) 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 N, it will also not work properly. In this case, a high-performance solenoid valve should be used.

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

(6) In addition, solenoid valves are generally installed horizontally. If they are installed on the side, it may cause the valve to not close tightly, i.e., internal leakage. Side installation should be avoided as much as possible [1]

Common faults of ATOS solenoid valves: An ATOS solenoid valve consists of an electromagnetic coil and a magnetic core, and is a valve body containing one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes fluid to flow through the valve body or be cut off, thereby changing the direction of fluid flow. The electromagnetic components of the solenoid valve consist of a fixed iron core, a moving iron core, and a coil; the valve body consists of a spool, a spool sleeve, and a spring base. The electromagnetic 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 3-way, 2-position 4-way, and 2-position 5-way valves. Here, we'll first explain the meaning of "2-position": for a solenoid valve, it means energized and de-energized; for the valve it controls, it means open and closed.

A malfunction of an ATOS solenoid valve will directly affect the operation of switching and regulating valves. A common malfunction is that the solenoid valve does not operate. The following aspects should be checked:

1. The ATOS solenoid valve wiring is loose or the wire has come loose. The solenoid valve will not be energized. Tighten the wire.

2. If the ATOS solenoid valve coil burns out, disconnect the solenoid valve wiring and use a multimeter to measure. If an open circuit is found, the solenoid valve coil is burnt out. Causes include moisture in the coil causing 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 too few coil turns resulting in insufficient suction 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. ATOS 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 generally assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubrication, it is easy for it 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 lubrication.

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 gaskets or worn spool sleeves, 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 one switching interval, pause the switching system and address the issue at a later time.

Common Applications of ATOS Solenoid Valves:

ATOS solenoid valves use a single solenoid coil to generate magnetic attraction, which overcomes the spring pressure and actuates the valve core. They are simple in structure, inexpensive, and only function as on/off valves.

1. Solenoid valves: Used for on/off control of liquid and gas pipelines, they are two-position (DO) valves. Generally used for small pipelines.

2. Solenoid valves: Can only be used as on/off valves, they are DO valves and can only be used for small pipelines. Commonly found in pipelines DN50 and below, rarely found in larger pipelines.

ATOS Solenoid Valve Principle: When energized, electromagnetic force opens the pilot orifice, causing a rapid drop in pressure in the upper chamber. This creates a pressure differential around the closing element, with higher pressure at the bottom and lower pressure at the top. The fluid pressure pushes the closing element upward, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downward, closing the valve.

ATOS Solenoid Valve Features: High upper limit of fluid pressure range; can be installed arbitrarily (customization required), but must meet fluid pressure differential conditions.

2. ATOS solenoid valves are divided into six subcategories based on differences in valve structure, materials, and operating principles: direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot-operated piston structure.

3. ATOS solenoid valves are classified according to function: water solenoid valves, steam solenoid valves, refrigeration solenoid valves, cryogenic solenoid valves, gas solenoid valves, fire-fighting solenoid valves, ammonia solenoid valves, gas solenoid valves, liquid solenoid valves, miniature solenoid valves, pulse solenoid valves, hydraulic solenoid valves, normally open solenoid valves, oil solenoid valves, DC solenoid valves, high-pressure solenoid valves, explosion-proof solenoid valves, etc.
