Check valves with integrated screens safeguard pumps and piping by preventing backflow and filtering debris: Backflow Protection: Prevents reverse flow that could damage pumps or system components. Debris Filtration: Captures particles before they enter critical system areas, reducing clogging and maintenance needs. Broad Applications: Commonly used in water supply systems, chemical processing, HVAC, and industrial automation. By combining anti-backflow functionality with filtration, these valves improve both system reliability and operational efficiency. https://www.xianyunvalve.com/product/check-valve/
