Overview

SHF(L)-70-911-20 is a high‑performance four‑way reversing valve specially designed for commercial HVAC, central air conditioning and air‑source heat pump systems. The valve precisely switches the internal refrigerant flow direction to complete automatic conversion between cooling mode and heating mode, realizing seasonal temperature adjustment and system cycle reversal. Adopting high‑strength valve body structure and precision internal spool design, it features stable reversing action, low flow resistance and excellent pressure resistance. The product is compatible with multiple mainstream environmental‑friendly refrigerants, perfectly adapted to variable‑frequency unit load changes and complex fluctuating operating conditions. With reliable sealing performance, anti‑vibration structure and long service life, it effectively improves the overall operating efficiency and operational stability of HVAC refrigeration and heat pump systems.
