The mechanically self-operated flow rate controllers VRW are designed for supply pressure-independent constant flow rate control without external power supply in round air lines of air-conditioning systems.
Constant flow rate controller in round design, mechanically self-actuating (no external power required), impervious to soiling
- 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
