Airtac 4V210-08A AC220V Solenoid Valve | 5/2 Way | In Stock

1. Core Advantages

The Airtac 4V210-08 AC220V solenoid valve is often used in heavy-duty industrial machinery that requires high power, a fast response speed, or long-distance power supply. AC power can provide instantaneous high power, and its operating principle (using a shading coil to eliminate vibration) makes it perform exceptionally well in specific applications.

2. Product Features

• High Power and Fast Response: AC power can provide high power, enabling fast response and switching, making it suitable for industrial applications that demand high speed.

• Advantage for Long-Distance Power Supply: AC power is ideal for long-distance cable transmission, as the voltage does not easily drop. This makes it a great choice for equipment in large factories.

• Stable and Reliable: The product undergoes strict testing to ensure stable operation in a variety of industrial environments.

Frequently Asked Questions

1. What are the main features of the AC220V version?

The main feature of the Airtac 4V210-08 AC220V solenoid valve is its use of 220V AC power. This voltage version is typically used in industrial environments that require high power or a long-distance power supply. It has a fast response speed and can provide instantaneous high power to drive the spool to switch quickly, making it especially suitable for use in large workshops and heavy-duty machinery.

2. What is the difference between the AC220V and DC24V versions?

This is the most common question. The main differences are:

• Voltage and Safety: AC220V is a high voltage, which makes it less safe than DC24V. More stringent electrical safety measures are required for installation and use.

• Power Consumption and Heat: The power consumption of AC220V (3.5VA) is slightly higher than that of DC24V (3.0W). The AC coil also produces a slight "humming" sound during operation and generates relatively more heat.

• Application Scenarios: AC220V is often used for heavy-duty machinery, pump and valve control, and other applications where direct factory power is available. DC24V is the preferred choice for low-voltage control systems like PLC control cabinets and automation production lines.

• Performance: AC solenoid valves generally have a faster response speed, while DC solenoid valves offer better anti-interference capabilities.

3. Why does the AC220V solenoid valve's coil make a "humming" sound when powered on?

This is a normal phenomenon. The nature of alternating current means the coil's magnetic field pulsates. The magnetic core vibrates with the current frequency (e.g., 50Hz), which produces this "humming" sound. As long as the sound is not excessively loud and doesn't affect normal operation, there is no need to worry. If the sound is unusually loud or harsh, you may need to check if the voltage is stable or if there is foreign matter inside the valve body.

4. What should I pay attention to when wiring an AC220V solenoid valve?

• Disconnect Power: Always completely cut off the power supply before any wiring operation to prevent electric shock.

• Follow the Wiring Diagram: Strictly follow the product's wiring diagram. Typically, there are two power lines, and polarity does not matter.

• Ensure a Firm Connection: Make sure the cables are tightly connected to the terminals to prevent heating or burnout due to poor contact.

• Avoid Crossover: If both AC and DC voltages are used in the same equipment, the cables must be properly isolated to prevent interference or short circuits.

5. If the solenoid valve is not working, how can I troubleshoot it?

Similar to the DC24V version, you can follow these steps for troubleshooting:

• Check the Power Supply: Ensure the power voltage is stable within the AC220V (±15%) range.

• Check the Coil: If there is no clicking sound when power is applied, the coil may be burned out or have an open circuit. You can use a multimeter to measure the resistance to check.

• Check the Air Supply: Confirm that the air pressure and cleanliness meet the requirements.

• Check the Valve Body: Check for any debris stuck in the valve spool or for damaged seals.
