Ball valve

manualelectrically-operatedhydraulically-operated

Ball and Spherical Valves Mainly used in hydroelectric power plants when high values of flow rate speed and/or pressure rating are required. Functions ■ maintenance operation ■ emergency / safety closing operation ■ as penstock valve The main feature of the valves produced by Nencini is the actuation of the two movable seal rings, one on upstream and one on downstream side of the valves. They ensure the perfect tightness of the valve and in the same time the upstream one can be used as maintenance tool to work on the downstream one. Applications ■ hydraulic power plants ■ discharge systems ■ pumping stations.
