The valves feature a balanced flow port design that supports stable operation in reversible systems, along with a compact form factor suited to tight installation spaces. Their fast, energy-efficient actuation helps optimise system performance across a broad refrigerant portfolio, including low GWP and flammable options such as R32, R290, R1234ze(E), and R1234yf.
Fully compatible with Sanhua SEC controllers, the DBF series is positioned as a next-generation solution for OEMs seeking higher efficiency, reliability, and flexibility in modern heat pump and AC platforms.
