28 Inch Check Valve, with a 28-inch nominal pipe size (roughly DN700), refers to a check valve that ensures one-way fluid flow while preventing backflow in extensive pipelines. Such a valve is widely used in critical applications, including offshore oil platforms and water supply networks, for fluid flow direction control.
