ENG-93001-93621-08.04-1M • Printed in Switzerland • ZSD • Subject to technical modifications BC 13 H5..B globe valves, 3-way, with external thread Applications • Water-side control of air handling units • Water-side control in heating systems Mode of operation The globe valve is operated by an NV series linear actuator. 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 30/31 • 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. • For pipe connectors as accessories, refer to page 6 Selection: H5..B kVS [m3/h] DN [mm] 3-way Suitable linear actuator, 3-point Suitable linear actuator, modulating DC 0 ... 10 V Suitable linear actuator, modulating DC 0 ... 10 V with emergency control function 1) Recommended for DN 32 – DN 50 and high closing pressures 2) Valve closed when deenergized 3) Valve open when deenergized Flow media Cold and warm water, water with max. 50% volume of glycol Temperature of medium (–10°C) +5°C...+120°C (–10°C on request) Rated pressure ps 1600 kPa (PN 16) Flow characteristic Control path A–AB: equal-percentage (to VDI/VDE 2173) n(ep) = 3, optimized in opening range Bypass B–AB linear (to VDI/VDE 2173) Rangeability DN 15 Sv > 50 DN 20...50 Sv > 100 Leakage rate Control path A–AB: max. 0.05 % of kvs value Bypass B–AB: max. 1 % of kvs value Pipe connection External thread to ISO 228 Differential pressure Äpmax 400 kPa Closing pressure Äps See table on page 8 Stroke 15 mm Valve closing point Up (Ä) Installation position Vertical to horizontal Maintenance Maintenance-free Materials Fitting Valve cone Valve seat Valve stem Stem gland seal Red casting brass Rg5 Brass Red casting brass Rg5 Stainless steel EPDM O-ring Technical data H5..B Dimensions: H5..B DN Stroke Dimensions [mm] External thread Weight [mm] [mm] L B H G kg 15 15 80 55 46 G 1 1/8” 1.1 20 15 90 55 46 G 1 1/4” 1.2 25 15 110 55 52 G 1 1/2” 1.4 32 15 120 55 56 G 2” 2.0 40 15 130 60 65 G 2 1/4” 2.5 50 15 150 65 65 G 2 3/4” 3.5 A 3-way valve can be converted to a 2-way valve by sealing port B with a blind plug.
