The Y-type filter is an essential component of a pipeline system that transports fluids. It is typically installed at the inlet of pressure-reducing valves, pressure-relief valves, water level control valves, or other equipment. Its purpose is to remove particulate impurities from the medium, protecting against blockages and damage caused by debris, rust, or welding residue within the pipeline. This helps avoid repair costs and production losses, ensuring the proper functioning of valves and other equipment.
