Differential Pressure Valve
Flow-limiting dynamic balancing valve · TEB-25
The dynamic balancing differential pressure control valve balances the building's heating system so every floor receives the same heat. It needs no power, prevents noise caused by high flow and pressure, and avoids unnecessary by-pass so pumps work less. Combined with thermostatic radiator valves, savings no longer depend on user habits.
Features
A proportional valve that compensates pressure differences between floors.
- Proportional control that needs no auxiliary energy.
- Hydronically balances the building's heating installation.
- Smooth, even heat distribution.
- Guarantees the flow required in the heating circuit.
- Prevents noise caused by high flow and pressure.
- Avoids unnecessary by-pass so pumps run less.
- Factory setting 10 kPa.
- Fits horizontally or vertically on the return line.
- Setting range 5–25 kPa; 1 kPa per turn, 20 turns in total.
- Precise control in buildings with thermostatic radiator valves.
- Automatic savings independent of user habits.
- Can be re-adjusted in existing systems.
