DVD Valves’ new Needle Valve provides cavitation-free, silent and non-vibrating regulation of pressure, flow and level thanks to its circular cross-sectional area on all disc positions. In the fully closed position, it provides drip-tight sealing and in fully open position it provides maximum flow capacity. The new valve is available ranging from DN 65 to DN 1200 currently, but sizes larger than 1200 mm will be available in the near future. In all sizes, it is produced from a single body so there is no need for another body connection to the main body in larger sizes, which decreases the weight and size of the valve while eliminating possible leakage points. The plunger is free from the pressure on the line and the welded disc rails provide low friction loss, meaning the valve can be operated at low torque values.
