A Detailed Analysis of the Airtac 4V210 Solenoid Valve: Structure and Operating Principle
Share
I. Introduction to the Airtac 4V210 Solenoid Valve
Airtac is a globally renowned brand in pneumatic components, and its 4V series solenoid valves are celebrated for their high performance, stability, and reliability. The 4V210 is a standard five-port, two-position solenoid valve widely used in automated equipment control systems to manage the extension, retraction, and switching of pneumatic cylinders. Featuring a fast response time, long service life, and low energy consumption, it is one of the premier choices for industrial automation and pneumatic control.
The 4V210 is characterized by its compact size, large flow capacity, and sensitive response. It is suitable for installation in diverse applications such as automated equipment, production lines, packaging machinery, labeling machines, and CNC processing systems, enabling precise pneumatic control.
II. Internal Structure Analysis
The Airtac 4V210 solenoid valve is primarily composed of the following parts:
-
Valve Body: Constructed from high-strength aluminum alloy, offering corrosion resistance and high-pressure tolerance.
-
Coil Assembly: Consists of a copper-wound coil and an enclosure, responsible for receiving electrical signals to drive the valve spool.
-
Spool and Spring: The core components that control the switching and flow of air.
-
Sealing System: Prevents air leakage, ensuring airtightness and durability.
This structure allows the valve to maintain stable airflow distribution during switching and reduces mechanical wear, thereby extending its operational lifespan.
III. Operating Principle Explained
When the coil is energized, the electromagnetic force moves the slide spool, which changes the direction of the airflow and switches the cylinder's action. When de-energized, the spring returns the spool to its original position, restoring the air path to its initial state and achieving an automatic reset.
The entire process typically has a response time of less than 0.05 seconds, enabling high-speed action responses in automated production lines.
Simplified Principle:
-
Energized: Spool shifts → Port A opens, Port B closes → Cylinder extends
-
De-energized: Spool resets (spring return) → Port B opens, Port A closes → Cylinder retracts
This is the two-position, five-port control logic of the 4V210 solenoid valve.
IV. Main Application Scenarios
The Airtac 4V210 is extensively used in:
-
Automated robotic arm motion control
-
Packaging and sealing machinery
-
Pneumatic sorting devices
-
Industrial assembly lines
-
Electronics assembly and automated inspection systems
It is valued for its small footprint, ease of installation, and strong compatibility, allowing it to be used in conjunction with various pneumatic components like cylinders and pressure regulators.
V. Usage Precautions
-
During installation, ensure the air source direction matches the markings on the valve body.
-
The coil voltage must match the supply (commonly DC24V or AC220V).
-
Avoid long-term exposure to high-temperature or high-humidity environments to prevent coil aging.
-
Regularly clean the valve body and filtering devices to ensure unobstructed airflow.
-
If the valve's action becomes sluggish, check if the air pressure is normal or if the seals are worn.
VI. Summary
The Airtac 4V210 solenoid valve has earned the trust of users worldwide due to its high sensitivity, stability, and durability. Its rational design and rapid response make it an ideal choice for industrial automation and pneumatic control. If you require a high-performance and easy-to-maintain solenoid valve, the Airtac 4V210 offers an excellent, cost-effective solution.
