ASCO Solenoid Valve Technical Parameters:

ASCO solenoid valves have through holes at different positions, each leading to a different oil pipe. The valve is located in the center of the chamber, with two electromagnets on either side. When the coil of one electromagnet is energized, the valve body is attracted to that side. By controlling the movement of the valve body, different drain holes are blocked or opened. The inlet hole is always open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston in the hydraulic cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the current to the electromagnets controls the mechanical movement.

Tracing its development history, domestic and international valves can be broadly categorized into three main types based on their operating principles: direct-acting, step-direct-acting, and pilot-operated. Furthermore, based on differences in valve disc structure and materials, and their operating principles, they are further divided into six subcategories: direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot-operated piston structure.

ASCO JOUCOMATIC, a member of the Fortune 500 company Emerson Group, is a multinational corporation primarily manufacturing and selling fluid control valves and pneumatic control components. With over 100 years of manufacturing experience and more than 30 factories worldwide, it provides customers with over 23,000 fluid control products. ASCO owns numerous brands, including ASCO/RED HAT and SIRAI, which include general-purpose products and some products suitable for special industrial applications, capable of controlling common media.

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

ASCO Solenoid Valve Selection Basis:

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

1) Determine the nominal diameter (DN) based on the on-site pipeline inner diameter or flow requirement;

2) For the connection type, 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 Type

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 preferable for convenience.

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 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, normally open types cannot be selected; continuously energized types should be chosen. These are available in direct-acting, pilot-operated, and manual reset types.

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