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 rotation of the magnetic core causes the flow to pass through the valve body or be cut off, thereby changing the flow direction. The electromagnetic components of the solenoid valve consist of a stationary 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 2-way and 2-position 3-way valves. The term "two positions" refers to energized and de-energized states for a solenoid valve, and open and closed states for the valve it controls. When current flows through the coil, it generates an excitation effect, attracting the moving iron core to the fixed iron core. The moving iron core then drives the spool valve core and compresses the spring, changing the position of the spool valve core and thus changing the direction of the fluid. When the coil is de-energized, the spring force pushes the spool valve core back, causing the fluid to flow in its original direction.

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

(1) The solenoid N terminal is loose or the wire is detached. 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. "(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 N, 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.

ATOS Solenoid Valve DKI Series Product Introduction

ATOS solenoid valve selection should first follow the four principles of safety, reliability, applicability, and economy. Secondly, it should be selected based on six aspects of the on-site working conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, operating mode, and special requirements).

ATOS Solenoid Valve Selection Basis: 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, >DN50 requires a flange connection; ≤DN50 can be selected freely according to user needs.

2. Selecting a solenoid valve based on fluid parameters: Material and temperature group
