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.
