CHECK VALVES

CNLD check valves are designed to prevent reverse flow and protect pipelines in industrial systems. By allowing fluid to flow in only one direction, these valves automatically stop reverse flow for safety purposes and equipment protection. Whether in wastewater treatment, mining, or general industrial process systems, a check valve is required to prevent backflow and ensure stable operation. CNLD offers high-performance swing, lift, and wafer check valves made from stainless steel, ductile iron, and carbon steel, with pressure ratings from PN10 to PN40. If you’re wondering what a check valve does, it keeps your media moving forward, clean, and controlled.
