HRB 3/HRB 4 Rotary Valve
Brand: Danfoss
Danfoss HRB rotary valves are primarily designed for regulation of flow temperature in heating systems where a certain leakage can be accepted and where a defined control characteristic is not required.
HRB rotary valves can be used in combination with electric actuators AMB 162 and AMB 182.
Features- Lowest leakage in class
- Unique position indicator (visible also when actuator in mounted)
- Ergonomic handle
- Easy installation
- For mixing and diverting applications
- Internal thread connection
