Acvatix™ 2-port valves, PN16 VVI46..
Use ● ● For use in ventilation and air-conditioning systems for water-side terminal unit control in closed circuits, e.g. for induction units, fan-coil units, small reheaters and small recoolers.
ΔPv100 = Differential pressure across the fully open valve and the valve's control path A ￫ AB by a volume flow V̇ V̇100 = Volume flow through the fully open valve (H100) ΔPmax = Maximum permissible differential pressure across the valve's control path, valid for the entire actuating range of the motorized valve 100 kPa = 1 bar ≈ 10 mWC 1 m3/h = 0.278 l/s water at 20 °C Type summary Type Stock number DN Connections PN class KVS A→ AB [m3/h] VVI46.15/3 S55249-V113 15 VVI46.
Example: Type Stock number Product name Quantity VVI46.15/3 S55249-V113 2-port zone valve, PN16 DN15, kvs 2.15 1 Delivery The valves and actuators are delivered in separate packaging. Order actuator SUE21 separately. Revision number See Revision numbers [➙ 8]. Equipment combinations Valves Motoric actuators SUE21 ΔPmax [KPa] ΔPS [KPa] VVI46.15/3…20/3 400 400 VVI46.
Notes Mounting Orientation ● ● ● The specified direction of flow must be observed in all cases (refer to Engineering [➙ 5]). The mounting instructions are enclosed with the packaging. The valve and actuator are easily assembled directly on site. There is no need for special tools or calibration. AL50 supporting ring For VVI46.25/3, the AL50 supporting ring must be put into position before mounting the actuator SUE21 onto the valve. VVI46.15/3 and VVI46.
WARNING The direction of flow MUST be as indicated by the arrow, from A￫AB. Maintenance VVI46../3 valves require no maintenance. CAUTION When doing service work on the valve/actuator: ● ● ● Deactivate the pump and turn off the power supply. Close the shutoff valves. Fully reduce the pressure in the piping system and allow pipes to completely cool down. If necessary, disconnect the electrical wires.
