A DN850 Gate Valve is a gate valve used to control fluid flow in pipelines with a nominal diameter of 850 millimeters (about 34 inches). It employs a gate-like mechanism for substantial flow regulation and is preferred in applications that entail tight shutoff and minimal pressure drop, such as in water supply systems and oil refineries.
