ATOS Solenoid Valve DHI-0710 23 In Stock

ATOS solenoid valves have a sealed chamber with through-holes at different positions, each connecting to a different oil pipe. In the center of the chamber is a piston, and on either side are two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. By controlling the movement of the valve body, different drain holes are opened or closed. 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 current to the electromagnets controls the mechanical movement.

ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control automation. 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 desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system; commonly used types include check valves, safety valves, directional control valves, and speed control valves.

ATOS solenoid valves consist of an electromagnetic coil and a magnetic core, forming a valve body containing one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes flow through the valve body or is cut off, thus changing the flow direction. The electromagnetic components of a solenoid valve consist of a stationary iron core, a moving iron core, and a coil; the valve body consists of a spool, a 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" in solenoid valves refers to energized and de-energized states, and for the controlled valve, it refers to open and closed states. 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 fluid flow. When the coil is de-energized, the spring force pushes the spool valve core back, causing the fluid to flow in its original direction.

Selection Principles

ATOS Solenoid Valve

Safety:

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 cannot be used for ammonia valves.

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 pipe.

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. When the pressure is low, 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.

2. Piping Parameters

1) Select valve port and model according to the medium flow direction requirements and pipeline connection method;

2) Select the nominal diameter according to the flow rate and valve Kv value, or select the same as the pipeline inner diameter;

3) Working pressure difference: For low working pressure difference above 0.04 MPa, an indirect pilot-operated type can be selected; for low working pressure difference close to or less than zero, a direct-acting type or a step-by-step direct-acting type must be selected.

3. Environmental Conditions

1) The highest and lowest ambient temperatures should be within the allowable range;

2) In environments with high relative humidity or water droplets/rain, a waterproof solenoid valve should be selected;

3) In environments with frequent vibration, bumps, and impacts, a special type should be selected, such as a marine solenoid valve;

4) In corrosive or explosive environments, corrosion-resistant types should be selected based on safety requirements;

5) If space is limited, a multi-functional solenoid valve should be selected, as it eliminates the need for a bypass and three manual valves and facilitates online maintenance. 4. Power Supply Requirements

1) Select AC or DC solenoid valves according to the type of power supply. Generally, AC power is more readily available.

2) Prioritize AC220V or DC24V voltage specifications.

3) Power supply voltage fluctuations are typically +10% to -15% for AC and ±10% for DC. If these fluctuations exceed these limits, voltage stabilization measures must be taken.

4) Select the rated current and power consumption according to the power supply capacity. Note that AC starts up with a higher VA value; if the capacity is insufficient, indirect-acting solenoid valves should be prioritized. DHI-0630/2/A-X 24DC 23
