AirTAC 4V Series Solenoid Valves: The Core Power of Fluid Control in Industrial Automation

Introduction

In the fluid control circuits of industrial automation, the solenoid valve acts as the "core command executor." Its response speed, stability, and durability directly determine the efficiency of the entire production line. With decades of technological expertise, AirTAC's 4V Series solenoid valves have become a mainstream choice in global industrial settings. Covering specific models like the 4V100, 4V200, 4V300, and 4V400, the series can precisely adapt to everything from miniature equipment to large-scale production lines. This article will thoroughly analyze the core technical advantages of the 4V Series and reveal why it has become the "power heart" of industrial automation.

 

I. Core Technical Characteristics of the 4V Series: Deconstructing the Underlying Logic of Efficient Control

1. Internal Pilot Structure: The Perfect Balance of Low-Pressure Start and High Flow

 

The 4V Series adopts an internal pilot design, eliminating the need for an external pilot air source. It relies solely on the pressure difference across the spool ends to drive commutation. The starting air pressure is as low as 0.15MPa, making it compatible with low-pressure pneumatic systems. Furthermore, models like the 4V410-15 achieve large-flow output via an effective cross-sectional area of 50mm. Compared to external pilot solenoid valves, the structure is more compact, saving 30%of installation space while eliminating the leakage risk associated with external pilot tubing.

 

2. Spool-Type Sealing Design: Guaranteeing Millions of Leak-Free Cycles

 

The spool is precisely machined from stainless steel and features imported Fluorine Rubber (FKM) seals, forming a sliding spool-type sealing structure. The sealing surface is mirror-polished, achieving a friction coefficient of 0.03$ and a mechanical lifespan of over $7.5 million cycles (some models exceed $10$ million cycles). Within the working pressure range of 0.15 sim 0.8MPa}, the air tightness is 10mL/min. Even in scenarios requiring continuous high-frequency operation (up to 3 times/second), it prevents leakage and ensures stable system pressure.

 

3. Lubrication-Free Design: Lowering O&M Costs and Adapting to Clean Environments

 

The 4V Series solenoid valves do not require supplementary pneumatic oil lubrication; they operate stably with only 40mu mfiltered clean air. This design not only simplifies air source preparation and reduces O&M costs (saving an estimated $30 annually on lubrication oil and filter element replacements) but also makes it suitable for scenarios with high cleanliness requirements, such as food processing and medical equipment, preventing oil contamination of products or the environment.

 

4. Multi-Voltage Adaptation + IP65 Protection: All-Scenario Compatibility

 

The series supports full voltage specifications, including AC 220V,AC 110V, AC 24V, DC 24V, and DC 12V. The coil insulation class is F-grade (temperature resistance 155C, and the permissible voltage fluctuation range is pm 10im pm 15%, accommodating different regional power grids and equipment control systems. Furthermore, the valve body's protection rating reaches IP65 (dust-tight and protected against low-pressure water jets). This ensures stable operation without environmental interference, even in dusty, humid workshops or outdoor equipment.

 

II. Typical Application Scenarios for the 4V Series: From Single-Point Control to System Integration

 

 

1. Automotive Manufacturing: The "Precise Executor" for Welding Robots and Assembly Lines

 

In automotive body welding production lines, models like the 4V210-08 and 4V310-10 are controlled by PLCs to drive cylinders, achieving rapid retraction and precise positioning of welding guns with a response time of $\le 0.05$ seconds, ensuring welding accuracy errors of $\le \pm 0.1\text{ mm}$. In new energy vehicle battery assembly lines, the 4V410-15 model utilizes its high-flow advantage to drive large-bore cylinders for handling and pressing battery modules, maintaining $12$ hours of continuous, fault-free operation per day.

 

2. Electronics Manufacturing: The "Micro-Control Expert" for Precision Equipment

 

In electronic component sorting equipment, miniature models like the 4V110-06 control air grippers for precise, damage-free grasping of chips and resistors, featuring an effective area of $8\text{ mm}^2$. In semiconductor wafer handling systems, the lubrication-free design of the 4V210-08 prevents oil contamination of the wafers, and its IP65 protection is ideal for cleanroom environments, ensuring high production yield.

 

3. General Machinery: The "Efficiency Engine" for Packaging and Printing Equipment

 

In food packaging machines, the 4V310-10 controls the synchronous motion of cutting blades and conveyor belts, maintaining stability under high-frequency commutation (2 times/second). In printing press ink path control, its precise flow regulation capability ensures even ink coating, reduces color difference, and improves product quality rate.

 

III. 4V Series Selection Key: Matching Core Parameters to Scenario Needs

 

  1. Effective Cross-Sectional Area (Cv Value): Select based on the air consumption of the actuator (cylinder, gripper). Small cylinders (bore $\le 32\text{ mm}$) match the 4V100/4V200 series ($\text{Cv} = 0.5 \sim 1.0$), while large cylinders (bore $\ge 63\text{ mm}$) should select the 4V300/4V400 series ($\text{Cv} = 1.5 \sim 3.0$).

  2. Voltage Specification: DC voltages (e.g., DC 24V, DC 12V are suitable for mobile equipment or low-voltage control systems, requiring attention to polarity. AC voltages (e.g., AC 220V, AC 110V are non-polar and suitable for mains power or industrial centralized power supply.

  3. Port Size: G1/8" (4V100 series), G1/4" (4V200 series), G3/8" (4V300 series), G1/2" (4V400 series). This must match the piping specifications to avoid excessive airflow resistance.

Summary

The AirTAC 4V Series solenoid valves leverage "Internal Pilot Structure, Spool Sealing, Lubrication-Free Design, and Multi-Scenario Adaptation" as their core advantages. They resolve the industrial dilemma of balancing "low-pressure start with high flow" and reduce O&M costs through a long-lifespan design. From automotive manufacturing to electronic precision machining, and from general machinery to new energy equipment, the 4V Series is consistently the "reliable partner" for industrial automation fluid control.
