①. Meanings of Pneumatic Solenoid Valve Models
Pneumatic valve solenoid valves are key components for controlling the opening and closing of pneumatic valves. Their models are usually composed of multiple letters and numbers, representing different parameters and specifications. The following table shows the common pneumatic valve solenoid valve models and their meanings:
| Model | Meaning
|
| 4V210-08 | "4" stands for 4-way 2-position, "V" for pneumatic valve solenoid valve, "210" indicates a diameter of 21mm, and "08" indicates an aperture of 8mm |
| 3V210-06 | "3" stands for 3-way 2-position, "V" for pneumatic valve solenoid valve, "210" indicates a diameter of 21mm, and "06" indicates a hole diameter of 6mm |
| 4V310-08 | "4" stands for 4-way 3-position, "V" for pneumatic valve solenoid valve, "310" indicates a diameter of 31mm, and "08" indicates a hole diameter of 8mm |
| 3V310-10 | "3" stands for 3-way 3-position, "V" for pneumatic valve solenoid valve, "310" indicates a diameter of 31mm, and "10" indicates a hole diameter of 10mm |
②. Parameters and Specifications of Pneumatic Valves and Solenoid Valves
There are various parameter specifications for pneumatic valves and solenoid valves, including diameter, hole diameter, working pressure, and the medium used. The following table shows the main parameter specifications of common pneumatic valves and solenoid valves:
| Parameter | Specification |
| passage diameter | 21mm, 31mm, 50mm, etc |
| Aperture | 6mm, 8mm, 10mm, etc |
| Work pressure | 0.15 ~ 0.8 MPa |
| Use medium | Compressed air, inert gases, steam, etc |
③. Common Faults and Handling Methods
Common faults of pneumatic valves and solenoid valves include air leakage, inability to open or close, and electrical leakage. The handling methods are as follows:
1. Air leakage: Check whether the solenoid valve is installed correctly and whether there are cracks, wear, or other problems on the sealing surface.
2. Unable to switch: Check whether the electromagnet and mechanical parts are stuck, damaged, or have other issues.
3. Leakage: Check whether the contacts of the solenoid valve are oxidized and whether the circuit is disconnected.
④. Summary
This article introduces the model meaning and parameter specifications of pneumatic valve solenoid valves, including common models and main parameters. It has certain reference value for relevant practitioners and enthusiasts. At the same time, attention should be paid to the use and maintenance of solenoid valves to ensure the normal operation of the equipment.
