Overview

SHF‑50B‑911D2 4‑way reversing valve is a core refrigerant flow‑control component for HVAC heat pump and air‑conditioning systems. Driven by pilot capillary tubes, the internal spool completes reversing action to quickly change refrigerant flow direction and realize cooling‑heating mode switch. It adopts brass body and high‑purity copper connecting tubes with high pressure resistance and good refrigerant corrosion resistance. Compatible with mainstream refrigerants such as R22, R410A, R407C. Suitable for small‑medium air‑cooled heat pumps and multi‑split air‑conditioning units, for OEM assembly and aftermarket replacement. It performs steadily under alternating temperature‑pressure conditions to guarantee stable circulation of the whole HVAC refrigeration system.
