Self-Filtering Fully Welded Ball Valve with Inner Strainer (GLQ61F)

**Product Information** One Piece Body Self-Filtering Fully Welded Ball Valve (You can also get the complete details in our company website as following: http://www.chinavalve1.com/product/Fully-Welded-Self-filtering-Ball-Valve.html) **Technology Background** In fluid transmission pipelines, ball valves are essential cutoff devices. To remove impurities and dirt from the media and ensure clean and unobstructed flow, filters are crucial. However, traditional filters installed in pipelines often take up a lot of space and are difficult to maintain. This new self-filtering fully welded ball valve solves these issues by offering a compact design, easy maintenance, and efficient filtration. **Technical Features** - Integrated welding structure prevents external leakage. - The valve seat is made of carbonized Teflon seal ring and spring, ensuring strong adaptability to pressure and temperature changes. - The ball is manufactured using advanced computer detection for high density. - The seal ring uses C-PTFE material with 20% carbon for zero leakage. - Compared to similar products, this valve is smaller, lighter, and more durable. - The filter network combines with the ball, acting as both a filter and a valve, reducing installation space and cost. - The V-shaped port ensures smooth media flow even when impurities block the filter. - A pressure relief valve design improves safety performance and allows for quick operation. **Parts List** Goole Self-Filtering Fully Welded Ball Valve – a multi-functional valve that acts as both a shut-off device and a filter, saving installation space and eliminating the need for a separate filter. It offers clean, simple, and convenient installation with a longer service life due to its fully welded structure. **Technical Parameters** - Nominal Diameter: DN65-DN350 - Nominal Pressure: PN1.6 - PN6.4 MPa - Applicable Temperature: -29°C ~ 200°C - Operation Method: Handle, Gear, Electric, Pneumatic - Applicable Media: Non-corrosive media such as water, gas, oil, etc. **Material Specifications** **Unique Design for Inner Strainer** Traditional filters can cause blockage and increase internal pressure. GOOLE’s V-Port design allows media to pass through while filtering impurities, preventing damage and extending valve life. The valve includes options for pressure relief via a pressure relief valve or threaded ball valve, making maintenance easier and safer. **Installation and Maintenance Instructions** - Ensure the valve arrow points in the correct flow direction. - Close the valve, open the flange cover, and remove the filter to clean or replace it. - For cleaning, release pressure, open the drain outlet, and remove debris. - Reinstall the cleaned filter and resume normal operation. **Dimension Table (PN 25, Handle Operated)** **Dimension Table (PN 25, Gear Operated)** Please confirm the size when ordering. **Contact Details** Ms Cathy Mobile: 008613868628912, 008615057596965
