ATOS Solenoid Valve Selection Considerations:

ATOS solenoid valve selection should first follow four principles in order: 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. Selecting 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) Connection method: Generally, >DN50 requires a flange connection; ≤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; when the minimum working pressure difference is 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 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 types cannot be selected; continuously energized types should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, check valve, manual operation, waterproof mist, water spray, submersible.

ATOS Solenoid Valve Selection Principles:

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 applications with infrequent operation. 1. Copper cannot be used for ammonia valves.

2. Explosive atmospheres: Appropriate explosion-proof products must be selected. For outdoor installations or dusty environments, waterproof and dustproof models should be selected.

3. The nominal pressure of the ATOS solenoid valve should exceed the maximum working pressure in the pipeline.

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, a multi-functional solenoid valve should be used when the nominal diameter is greater than 15 mm; a high-viscosity solenoid valve should be used when the nominal diameter is less than 15 mm.

4) When the media cleanliness is not high, a backwash filter valve should be installed before the solenoid valve. For low pressure, 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 the valve port and model based on the medium flow direction requirements and pipeline connection method;

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

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

ATOS Solenoid Valves

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 the desired control, while ensuring control accuracy and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most commonly used are check valves, safety valves, directional control valves, and speed regulating valves.
