The linear actuators are controlled by a standard modulating or 3- point control system and move the cone of the valve, the mixing device, to the opening position dictated by the control signal. Product features Equal-percentage characteristic Produced by the profiling of the valve cone. The bypass has a linear characteristic. Manual operation with NV actuator Using a hexagonal key to turn the actuator. • For installation instructions, refer to pages 30…32 • For closing pressure / differential pressure, refer to page 8 • Sizing diagram for globe valves, refer to page 9 • The information provided on pages 33/34 regarding operation, installation, project design, commissioning and maintenance must be strictly observed. 3-way globe valves with flange DN 15...150 For the modulating control of cold and warm water Dimensions: H7..N DN Stroke Actuator Dimensions [mm] Flange Weight [mm] [mm] Type L B H D K d C kg 15 15 NV.. 130 65 46 95 65 4x14 14 2.8 20 15 150 70 46 105 75 4x14 16 3.7 25 15 160 75 52 115 85 4x14 16 4.7 32 15 180 95 56 140 100 4x18 18 7.2 40 15 200 100 64 150 110 4x18 18 9.2 50 15 230 100 64 165 125 4x18 20 12.2 65 18 290 120 100 185 145 4x18 20 19.0 80 18 310 130 110 200 160 8x18 22 24.0 65 30 AV.. 290 120 100 185 145 4x18 20 19.0 80 30 310 130 110 200 160 8x18 22 24.0 100 30 350 150 125 220 180 8x18 24 34.0 125 40 400 200 281 250 210 8x18 26 67.4 150 40 480 210 343 285 240 8x22 26 93.8 A 3-way valve can be converted to a 2-way valve by sealing port B with a blind flange.
