How does an ASCO valve work?

An ASCO valve, specifically an ASCO electromagnetic valve, operates based on the principle of electromagnetic force to control the opening and closing of the valve. Here’s a detailed explanation of how it works:

Basic Structure

Operating Principle

  1. When Power is On:
    • Electricity flows through the electromagnetic coil, generating a magnetic field.
    • The magnetic field attracts the moving core, causing it to move and open the fluid passage in the valve body.
    • This allows fluid to flow through the valve.
  2. When Power is Off:
    • The magnetic field disappears when the electricity is cut off.
    • The spring then pushes the moving core back to its original position, closing the fluid passage.
    • This stops the flow of fluid through the valve.

Types and Characteristics

ASCO valves come in various types, including direct-acting, distributed direct-acting, and pilot-operated. Each type has its unique characteristics:

Applications

ASCO valves are widely used in various industries and applications, including:

In summary, an ASCO valve works by utilizing the principle of electromagnetic force to control the opening and closing of the valve. Its basic structure includes an electromagnetic coil, valve seat, valve body, moving core, and spring. Depending on the type of valve, it can be used in a wide range of applications and industries.
