**Technology Background**
In fluid transmission pipelines, ball valves serve as essential shut-off devices. To remove impurities and maintain pipeline cleanliness, filters are commonly used. However, traditional filters require extra space and are difficult to clean and maintain. This new self-filtering fully welded ball valve solves these issues by integrating a filter into the valve body, reducing installation space and improving efficiency.
**Technical Features of the Self-Filtering Fully Welded Ball Valve**
- **Integrated Design:** No external leakage due to full welding.
- **Valve Seat:** Carbonized Teflon seal ring with spring for pressure and temperature adaptability.
- **Ball Manufacturing:** Advanced computer testing ensures high density and durability.
- **Seal Ring:** C-PTFE material with 20% carbon for zero leakage.
- **Compact Structure:** Smaller and lighter than similar products, ideal for various applications.
- **Filter Integration:** The filter is built into the ball, allowing one valve to perform multiple functions.
- **V-Port Design:** Ensures smooth media flow even when impurities are present.
- **Pressure Relief Option:** Can be configured with a pressure relief valve or a threaded ball valve for easy cleaning.
**Parts List (Material and Name)**
| Part Name | Material |
|-------------------------|-------------------|
| Valve Body | Carbon Steel |
| Ball | Stainless Steel |
| Filter | Stainless Steel |
| Drain Cover | Carbon Steel |
| Short Connection Pipe | Carbon Steel |
| Valve Seat | PTFE + C |
**Unique Design for the Inner Strainer**
Traditional filters often cause blockage and increase internal pressure. Our V-Port design allows media to flow freely while capturing impurities at the bottom, ensuring efficient operation and extended service life.
**Cleaning and Maintenance Methods**
- Close the valve and release pressure through the pressure relief valve.
- Open the drain outlet and remove impurities from the filter.
- Replace or clean the filter as needed and re-install it.
