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

ATOS Solenoid Valve Selection Basis:

1. Select the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection method

1) Determine the nominal diameter (DN) according to the on-site pipeline inner diameter or flow requirements;

2) For the connection method, generally, >DN50 requires a flange connection, while ≤DN50 can be freely selected according to user needs.

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

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel valves 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 DN25, these must be clearly distinguished.

4) Fluid viscosity: Generally, any viscosity 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 Structural Types

1) Nominal pressure: This parameter has the same meaning as other general-purpose valves and is 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 valve must be selected; for low working pressure differentials above 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected. 4. Electrical Selection: AC220V or DC24V voltage specifications are preferred for ease of use.

5. Selection Based on Continuous Operating Time: Normally Closed, Normally Open, or Continuously Powered

1) When the solenoid valve needs to be open for a long time, and the duration 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, a normally open type cannot be selected; a continuously powered type should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, Check Valve, Manual Operation, Water-resistant Fog, Water Spray, Submersible.

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. Common types include check valves, safety valves, directional control valves, and speed control valves.
