VB 2 2-Way Pressure Balanced Valve
Brand: Danfoss
VB 2 are two-way valves designed to work with Danfoss electric actuators AMV(E) 10, AMV(E) 20, AMV(E) 30 or Danfoss electric actuators with spring return function AMV(E) 13, AMV(E) 23 and AMV(E) 33.
The VB 2 valves are generally recommended for use in most demanding conditions in systems such as:
- District heating
- Heating
- Hot water service with heat exchanger or storage tank where they ensure long and unproblematic performance
- SPLIT characteristic developed for most demanding applications
- High closing Δp with small sized actuators
- Several kVS values
- Push connection for easy mechanical connection with actuator
- Control range min. 50:1
