ASCO solenoid valves consist of two basic functional units: a solenoid coil and a magnetic core. The valve body contains one or more orifices. When the coil is energized or de-energized, the movement of the magnetic core causes fluid to flow through the valve body or be cut off. The solenoid coil is directly mounted on the valve body, and the magnetic core is enclosed in a sealing tube, forming a simple and compact combination. ASCO pulse dust collector valves from the USA, including models SCG353A043, SCG353A044, SCG353A047, SCG353A051, SCG353.060, and SCXE353.60, are available in various specifications and models, some in stock, offering competitive quality and prices.

Technical parameters of ASCO solenoid valves:

They 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 of the hydraulic cylinder, which in turn moves the piston rod, which in turn moves the mechanical device. Thus, controlling the current to the electromagnets controls the mechanical movement.

Tracing its development history,

currently, domestic and international solenoid valves are classified into three main categories based on their principles (i.e., direct-acting, step-direct-acting, and pilot-operated). Based on differences in valve disc structure and materials, and differences in 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, it operates more than 30 factories worldwide, providing customers with over 23,000 fluid control products. ASCO owns numerous brands, including ASCO/RED HAT and SIRAI, which offer 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 of priority: safety, reliability, applicability, and economy. Secondly, selection should be based on six aspects of the on-site operating conditions (i.e., piping parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements).

ASCO Solenoid Valve Selection Criteria (USA):

1. Selection of Solenoid Valve Based on Pipeline Parameters: Nominal Diameter (DN) and Connection Type

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.

2) Connection type: Generally, for DN > 50, a flange connection should be selected; for DN ≤ 50, the connection type can be freely selected according to user needs.

2. Selection of Solenoid Valve Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel 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 should be chosen.

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN 25, which must be clearly distinguished.

4) Fluid Viscosity: Generally, any choice is acceptable 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 Structure

1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, 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 must be selected. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.

4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.

5. Selecting Based on Continuous Working 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 valves cannot be selected; a continuously energized type should be chosen. These are classified as direct-acting, pilot-operated, and manually reset valves.

6. Auxiliary functions can be selected according to environmental requirements: explosion-proof, backflow preventer, manual operation, waterproof mist, water spray, and submersible.
