4 Inch Check Valve

A 4 Inch Check Valve is a one-way valve designed for 4-inch pipelines (roughly equivalent to DN100). It ensures unidirectional flow control, preventing backflow within small to medium-scale pipelines, and is commonly used in wastewater treatment plants to maintain flow direction.
