The BTL Y-strainer, Model GL41H-16<\/strong>, is an important pipeline protection device that acts as a \u201cshield\u201d, removing dirt, gravel, rust, and other mechanical impurities from the fluid stream. Installing a Y-strainer directly upstream of measuring devices such as water meters, pressure reducing valves, check valves, or pumps helps prevent jammed impellers, scratched valve discs, and system damage. This keeps the entire pipeline running smoothly and safely for operators.<\/p>\n

Detailed construction of the BTL Y-strainer, Model GL41H-16<\/h2>\n

Like the other Y-strainers supplied by An Phu Thanh, this product has a body inclined at 45 degrees, flange connections to the BS4504 standard, and a construction of 5 main parts.<\/p>\n

4<\/td>\nO-ring<\/td>\nNBR\/EPDM<\/td>\nSeals between the cover and the valve body, preventing leakage at the assembly point<\/td>\n<\/tr>\n

The inclined design of the BTL Y-strainer gives lower pressure loss than a T-type strainer. The Y-strainer can also be installed both horizontally and vertically (on a pipeline with downward flow), making it easy to fit a wide variety of pipeline layouts.<\/p>\n
