Flow Rate Controller constant VRW/US

Maximum flexibility
maintenance-free
Position-independent installation

The mechanically self-operated flow rate controllers VRW/US are designed for supply pressure-independent constant flow rate control without external power supply in round air lines of air-conditioning systems.

The flow rate control is obtained through an asymmetrically angled regulating blade on friction-free bearings, ensuring a precision response and regulating action even at small flow rates.

  • Flow rate control without external power supply – no wiring required
  • Maximum flexibility – free setting of flow rates
  • Insensitive to dust or environmental influences – maintenance-free with reliable precision control
  • Particularly suitable for visible installation
  • Position-independent installation
