Two way valves 2TBB and three way valves 3TBB with bronze body can be used either for fluid control or detection in domestic hot water, air-conditioning, thermoventilation and heating plants, both environmental and industrial, and in machines for product thermal process. Three-way valves should be used only as mixing valves; angle way should never be usedfor control purposes.
2TBB are globe valves equal percentage characterised; the valve is closed when plug is lifted.
3TBB valves have a parabolic plug with modifi ed characteristic; if the plug is back the direct way is open. The angle way has a linear characteristic. It guarantees an excellent operation both as mixing as well as diverter valve.
These valves can be motorized by MVH and MVE actuators.
