$408.10
ATOS solenoid valve piping parameters: 1) Select the 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: Indirect pilot type can be selected if the lowest working pressure difference is above 0.04Mpa; Direct type or step-by-step direct type must be selected if the lowest working pressure difference is close to or less than zero.

ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation 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, such as check valves, safety valves, directional control valves, and speed control valves.
ATOS Solenoid Valve Safety:
1. Corrosive Media: Plastic King Solenoid Valves and All-Stainless Steel Valves are recommended; for highly corrosive media, diaphragm type valves must be used. 1. For neutral media, solenoid valves with copper alloy valve bodies are preferable; otherwise, rust particles will frequently flake off from the valve body, especially in applications with infrequent operation. Copper cannot be used for ammonia valves.
2. Explosive environments: Appropriate explosion-proof products must be selected. For outdoor installations or dusty environments, waterproof and dustproof models should be chosen.
3. The nominal pressure of the solenoid valve should exceed the highest working pressure in the pipeline.
ATOS Solenoid Valve 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 typically below 50 cSt. If it exceeds this value, a multi-functional solenoid valve should be used for a nominal diameter greater than 15 mm; a high-viscosity solenoid valve should be used for a nominal diameter less than 15 mm.
4) When the cleanliness of the medium 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 used.
5) If the medium flows in a directional manner and backflow is not allowed, a bidirectional flow valve is required.
6) The medium temperature should be within the allowable range of the solenoid valve.
ATOS Solenoid Valve Selection Criteria:
1. Select the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection type.
1) Determine the nominal diameter (DN) according to the inner diameter of the pipeline or flow requirements.
2) For the connection type, generally, a flange connection should be selected for DN >50, while for DN ≤50, the user can choose freely according to their 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 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.
