Selection criteria for solenoid valves:

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 on site;

2) For connection type, generally, flange connections should be selected for DN>50, while for DN≤50, the connection type 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.
