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
