Metal Seated Gate Valves are designed and manufactured for use in wastewater and sewage applications, Dutco Tennant’s gate valves are available in both Rising and Non-Rising Stem (NRS) and Outside Screw & Yoke (OS&Y) versions. Metal seated valves are used for isolation purposes and its primary application lies in Wastewater & Sewage operations. Metal seated solid wedge design is available in both rising & non-rising spindle.

The valve is featured with two independent seating surfaces and is fully bi-directional. The body is featured with a full free open passageway equal to the nominal line size to minimize pumping losses. The simple two moving component construction practically eliminates inadvertent damage. Valves are manufactured & tested in accordance with BS 5150 & AWWA.

Metal seated wedge gate valves are primarily designed for the flow isolation of a length of pipeline or piece of equipment. It uses a ductile iron gate that houses bronze rings to ensure a watertight seal. The non-rising stem design ensures that the stem thread is lubricated adequately by the water passing through the valve. The whole internals is water-dependent for lubrication, a factor that safeguards the longevity of the valve.
