Mechanical circular CAV regulator with external selector wrench

The VRK series of circular CAV flow regulators maintain a constant flow rate, to a tolerance of 5%, without the aid of external power and independently from the pressure and variations in airflow.

VRK series CAV flow regulators – VRK Model
The VRK circular flow regulators are designed for use in constant air volume (CAV) ventilation and airconditioning systems. They are used to maintain the pre-set flow rate, to a tolerance of 5%, without the aid of external power sources.

The airflow is adjusted by a set of blades that, as they are hit by the airflow, are operated by a spring that is set using a graduated scale on the outside of the terminal.
The air flow is calibrated in the factory based on the nominal value requested; if necessary, this value can be adjusted by micrometric adjustment of the spring.

  • Flexible use and inclusion in systems due to its specific flow-reading system.
  • Constant accuracy in all assembled positions.
