Italian ATOS solenoid valve SCLI-40313 in stock
$312.04
The Italian ATOS solenoid valve operates on a combination of direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, energizing the valve causes the electromagnetic force to lift the pilot valve and the main valve's closing element sequentially, opening the valve. When the inlet and outlet reach the starting pressure difference, energizing the valve causes the electromagnetic force to actuate the pilot valve, increasing the pressure in the lower chamber of the main valve and decreasing the pressure in the upper chamber, thus using the pressure difference to push the main valve open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.

ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control in automation systems. 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. There are many types of solenoid valves, each playing a different role in the control system. Common types include check valves, safety valves, directional control valves, and speed control valves.
ATOS Solenoid Valve Selection Criteria:
1. Selection of Solenoid Valve Based on Pipeline Parameters: Nominal Diameter (DN), Connection Type
1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.
2) Connection type: Generally, for DN > 50, a flange connection should be selected; for DN ≤ 50, the connection type can be freely selected according to user needs.
2. Selection of Solenoid Valve Based on Fluid Parameters: Material, 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 should be chosen.
3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN 25, which must be clearly distinguished.
4) Fluid Viscosity: Generally, any fluid can be selected below 50 cSt; if it exceeds this value, a high-viscosity solenoid valve should be selected. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structure
1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by the nominal pressure of the pipeline.
2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.
4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.
5. Selecting Based on Continuous Working Time: Normally Closed, Normally Open, or Continuously Energized
1) When the solenoid valve needs to be open for a long time, and the continuous time is longer than the closing time, a normally open type should be selected.
2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.
3) However, for some safety protection applications, such as furnace and kiln flame monitoring, normally open valves cannot be selected; a continuously energized type should be chosen. An ATOS solenoid valve consists of an electromagnetic coil and a magnetic core, and 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, let's 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.
