Sanhua has released its DBF series of electronic expansion valves for commercial air conditioning and heat pump systems. The new series is designed to provide precise, bidirectional refrigerant flow control in reversible systems.
According to the source, the DBF series uses a balanced flow port design to enable accurate bidirectional adjustment of refrigerant flow. It also offers a wide adjustment range to match the actual load of the system, with the aim of supporting operation in the best working condition.
The company said the valves support accurate temperature control, rapid cooling, heating and defrosting, while helping to reduce energy consumption. The series is also described as compact to install and fast in operation.
Sanhua said the DBF series is compatible with its SEC controllers and can be used with a range of refrigerants, including flammable options such as R32, R290, R1234ze(E) and R1234yf.
