Lianke Valves’ T strainers (tee strainers) provide robust pipeline protection by filtering debris like rust, weld slag, and particulates in industrial fluid systems. Designed for inline installation, these T-type strainers safeguard pumps, valves, and downstream equipment from clogging and damage, outperforming cast Y strainers in flow efficiency while maintaining cost-effective coarse filtration.

Y type Strainer is an indispensable filter device in the pipeline system of conveying media made by stainless steel. It is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed level valve or other equipment to remove impurities in the media to protect the normal use of valves and equipment. The characteristics include advanced structure, low resistance, convenient blowdown and so on. Applicable media can be water, oil, gas. Generally, the water network is 18 to 30 mesh, the ventilation network is 10 to 100 mesh, and the oil network is 100 to 480 mesh.
