WVK2 Rectangular Constant Air Volume Dampers

    • Product Details


      WVK2 volume flow rate controllers for air conditioning and ventilation systems, suitable for vertical and horizontal installation in supply and exhaust ducts. The casing and control mechanism are made of galvanised sheet steel. The centrally supported damper blade, which controls the volume flow rate, has a stainless steel bearing axis in special bushings. Adjustment device with rotary pointer, scale and lock for the volume flow rate set point and can be adjusted manually or by actuator.

      WVK2 Volume Flow Rate Controllers are mechanical controllers for constant volume flow rates and do not require an auxiliary power supply. A special control mechanism guarantees control accuracy over the entire volume flow range. Within this control range, specified at V min and V max the set point for the required volume flow rate is adjustable.

      The volume flow rate is maintained constant at varying pressures within the specified pressure range, with an approximate deviation of between ±5% and ±15% with greater deviations at lower flow rates, especially on the smaller sizes.
