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
