The Y-type filter is a common pipeline filtration device, named for its "Y"-shaped valve body. It is primarily used to intercept solid particles, rust, sand, and other impurities in fluids, thereby protecting downstream equipment such as pressure-reducing valves, pumps, and instruments from clogging or wear. It is typically installed at the inlet end of critical equipment and is widely applied in water treatment, central air conditioning, petrochemicals, power generation, metallurgy, and building heating systems. Structurally, it consists of a Y-shaped housing, a stainless steel filter screen (often a cylindrical filter basket), a flange cover, and fasteners, making it easy to disassemble and clean. Its design balances fluid dynamics performance and space efficiency, offering advantages such as compact structure, low flow resistance, and convenient sediment discharge. Based on connection methods, it can be categorized into flange type, threaded type, and welded type, adapting to different pressure ratings and media types, such as water, gas, and oil. The filtration precision typically ranges from 100 to 480 mesh/cm² and can be customized according to operating conditions. Some high-end models are equipped with differential pressure switches to monitor filter clogging in real time, alerting users when cleaning is needed to ensure continuous and stable system operation.

T-Type Filter (also known as T-type pipeline filter or three-way filter) is a critical in-line filtration device in industrial piping systems. Its core function is to efficiently remove solid particles, impurities, or sediments from fluid media without interrupting the process flow, thereby protecting downstream key equipment such as valves, instruments, and pumps from wear, clogging, or damage. Its structure is shaped like a "T," with the main pipeline serving as the straight-through flow path and the side branch as the filter cartridge cavity, housing a removable basket-type or wedge-shaped filter screen. When fluid enters the filter, impurities are trapped by the screen, while the cleaned medium flows out from the outlet. When accumulated impurities on the screen require cleaning, maintenance can be performed online without shutdown by opening the side branch flange or blind plate cover. Filters produced by KVC Valve Group are characterized by high flow capacity, low pressure drop, high dirt-holding capacity, and easy maintenance. Depending on the filter screen precision and medium characteristics, different materials and mesh specifications are available. They are widely used in industries such as petrochemicals, natural gas transmission, power generation, water treatment, and pharmaceuticals, typically installed upstream of pumps, instruments, and critical valve inlets.

A basket filter is a robust, high-capacity in-line filtration device designed for continuous operation in process systems. It efficiently captures and removes solid particles, welding slag, rust, and other mechanical impurities from liquid or gas media to protect downstream critical equipment such as pumps, compressors, flow meters, heat exchangers, and valves. The core structure of a basket filter consists of a cylindrical valve body and a cylindrical filter basket that can be fully removed for cleaning. It typically features a top flange cover for easy access. The medium enters the filter from the side inlet, flows through the inner and outer surfaces of the filter basket, where impurities are trapped inside the basket, and the cleaned medium exits through the outlet. When the basket accumulates impurities, the system can be shut down, the cover opened, and the basket removed directly for cleaning or replacement. Basket filters produced by KVC Valve Group are characterized by their sturdy construction, large filtration area, high flow capacity, low pressure loss, and ample dirt-holding space. Their design generally complies with pressure vessel standards such as ASME and ANSI, ensuring high pressure resistance. They are widely used in industries such as petrochemicals, oil refining, power generation, papermaking, food processing, and water treatment for applications including raw material transportation, product refinement, and protection of circulation systems.
