Belimo C620QPT-G+BAC - 6-way PI zone valve

Belimo C620QPT-G+BAC – 6-way PI zone valve

Device for closed water systems. The 6-way valve switches between cooling and heating sequences, while the 2-way PIQCV regulates flow according to the control signal. The maximum flows of both sequences can be set separately.
