A Y-type strainer removes debris and solid particles from liquids, gases, or steam in pipelines, protecting pumps, valves, and other equipment from damage. The strainer is named after its “Y” shape, which contains a mesh or perforated screen.
It allows fluid to pass through while trapping unwanted particles, which can be removed by cleaning the screen. Commonly used in water treatment, chemical processing, and HVAC systems, it helps ensure smooth operation and prevent blockages.

Fluorine-lined Y-type filter is a new type of filter product developed by our factory based on the advantages of filters and fluorine plastic-lined valves according to customer requirements.This product is suitable for: various concentrations of hydrochloric acid, sulfuric acid, hydrofluoric acid, aqua regia, nitric acid, various organic acids, strong alkalis, strong oxidants or concentrated dilute acids, various organic solvents and other highly corrosive media except molten alkali metals, elemental gases and aromatic hydrocarbons (Note: the applicable media of different lining materials are different).The shell material of this product is carbon steel lined with fluorine plastic, and the filter material is F46, F4 and other materials.This product has the advantages of strong corrosion resistance, high filtration efficiency, and easy maintenance.
It effectively traps and removes debris from the flow, protecting downstream equipment from damage and ensuring smooth operation.
The Y-shape allows for installation in tight spaces, making it suitable for systems with limited room for larger filtration devices.
Y-type strainers can be installed in both horizontal and vertical pipelines, providing flexibility in system design.
The strainer can be easily cleaned by removing the screen, reducing downtime and maintenance efforts.
Y-type strainers are typically built from robust materials, making them resistant to wear and capable of handling high-pressure applications.
