ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation 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.

ATOS solenoid valves contain a sealed chamber with through-holes at different positions, 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

Common 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 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 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. 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, thus changing the direction of fluid flow. The electromagnetic components of a 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

The selection of ATOS solenoid valves should first follow four principles in order: safety, reliability, applicability, and economy. Secondly, it should be based on six aspects of the on-site operating conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements).

ATOS Solenoid Valve Selection Criteria:

1. Selecting a Solenoid Valve Based on Pipeline Parameters: Nominal Diameter (DN) and Connection Type

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.

2) For connection type, generally, flange connections are required for DN > 50, while for DN ≤ 50, the user can choose freely according to their needs.

2. Selecting a Solenoid Valve Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.

2) High-Temperature Fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves are preferred.

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN 25, it is essential to distinguish between these states.

4) Fluid Viscosity: Generally, any fluid can be selected below 50 cSt. If this value is exceeded, a high-viscosity solenoid valve should be selected.
