Sanhua VPF valves now for flammable refrigerants

SPAIN: Sanhua has extended TÜV certification for its VPF electronic expansion valves to include larger models (sizes 50 to 400) — enabling their safe use with flammable refrigerants.

According to Sanhua, this expansion opens new possibilities for large-scale HVAC and refrigeration systems with cooling capacity from 50 to 3500kW, using low GWP refrigerants. 

VPF series electronic expansion valves are designed for commercial and industrial applications. Typical VPF applications are air conditioning and refrigeration systems or heat pumps enabling bidirectional operation to control the refrigerant flow rate in heating or cooling mode.
