ATOS Solenoid Valve Selection Principles:

1. Corrosive Media: Plastic-coated solenoid valves and all-stainless steel valves are recommended; for highly corrosive media, diaphragm-type valves must be selected. For neutral media, solenoid valves with copper alloy valve bodies are also recommended; otherwise, rust particles will often fall from the valve body, especially in infrequent applications. Copper valves cannot be used for ammonia applications.

2. Explosive Atmospheres: Products with the appropriate explosion-proof rating must be selected. For outdoor installations or dusty environments, waterproof and dustproof models should be selected.

3. The nominal pressure of the solenoid valve should exceed the maximum working pressure in the pipeline. ATOS Solenoid Valves

Applicability:

1. Media Characteristics

1) Different types of solenoid valves should be selected for gaseous, liquid, or mixed states;

2) Different specifications of products should be used for different media temperatures, otherwise the coil will burn out, the seals will age, and the lifespan will be severely affected;

3) Media viscosity is usually below 50 cSt. If it exceeds this value, use a multi-functional solenoid valve when the nominal diameter is greater than 15mm; use a high-viscosity solenoid valve when the nominal diameter is less than 15mm.

4) When the media cleanliness is not high, a backflush filter valve should be installed before the solenoid valve. For low pressure, a direct-acting diaphragm solenoid valve can be selected;

5) If the media flows in a directional manner and backflow is not allowed, a bidirectional flow valve is required;

6) The media temperature should be selected within the allowable range of the solenoid valve.

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 movement of the valve body 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. 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. The most common are check valves, safety valves, directional control valves, and speed control 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.

ATOS Solenoid Valves: Faults in the solenoid valve will directly affect the operation of switching and regulating valves. Common faults include the solenoid valve not operating. The following troubleshooting steps should be taken:

1. Loose or disconnected wiring at the solenoid valve connection point will prevent the valve from being energized. Tighten the wiring.

2. If the solenoid valve coil is burnt 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. If the solenoid valve is stuck: The clearance between the solenoid valve spool and the valve core is very small (less than 0.008mm), and they are usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubrication, it is easy for the valve to get stuck. 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 oil mist lubricator nozzles are clogged and if the lubricating oil level is sufficient.

4. Air Leakage: Air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve. This is caused by damaged gaskets or worn slide valves, resulting in air leakage between several cavities. When troubleshooting a solenoid valve malfunction in the switching system, 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, suspend the switching system and address the issue at a later time.
