I. Core Structural Features
- Structural Form Y-type flow path design (Y-shaped main body visible in the image). When the medium passes through, impurities naturally settle to the bottom drain port, integrating filtration and drainage functions;
- Connection Method Flange connection, flange dimensions conform to GB/T 9113 "Integral steel pipe flanges" ;
- Sealing Form Hard seal structure (metal sealing surface or metal-to-graphite), conforming to the sealing performance requirements of GB/T 12238;
- Filter Element Removable stainless steel (304/316) filter (conforming to GB/T 1220 "Stainless steel bars" ), optional filtration accuracy (18~300 mesh, suitable for water, oil, and gas media);
- Drainage Design A drain port is provided at the bottom for manual opening to quickly discharge impurities, facilitating maintenance.

V. Typical Application Scenarios
- Building water supply and drainage system Before water pumps, pressure reducing valves, and water meters, filter pipeline impurities to protect equipment;
- HVAC engineering Cooling water circulation pipelines, preventing sand and mud from clogging heat exchangers;
- Chemical pipelines Before transporting corrosive media (such as acid-base solutions), protect valves and pumps;
- Power industry Turbine circulating water system, filtering particulate matter in cooling water;
- Steam system Boiler feedwater pump inlet, to prevent rust and scale from entering the boiler.

Y-type strainer GL41H
The GL41H flange Y-type filter uses a Y-type flow path design, flange connection conforms to national standards, stainless steel filter screen achieves 18~300 micron precision filtration, and hard seal structure ensures zero leakage of the medium. Manual disassembly and cleaning are convenient, and the bottom drain port quickly drains impurities. It is suitable for water, oil, gas, steam and other media, and is widely used in building and industrial pipeline systems, effectively protecting downstream valves, pumps and other equipment, and improving system reliability and service life.
