DN40 Check Valve
DN40 Check Valve is a one-way valve designed to allow fluid or gas to flow in one direction only through a pipeline with a DN40 nominal diameter (about 1-1/2 Inch). This valve automatically prevents backflow while ensuring unidirectional fluid flow within small-sized piping systems, and is commonly used in plumbing systems and pump installations.
