Sanhua introduces SHF-G series stainless steel reversing valves for HVAC systems

Sanhua has launched the SHF-G series, a new line of four-way reversing valves designed for heat pump systems, including central and unitary air conditioners. The series supports cooling capacities from 4.2 to 77.3 kW and is compatible with a wide range of refrigerants, including R32, R290, R1270, R600a, and R744 (CO2).

Engineered for both fixed and variable speed systems, the SHF-G valves feature a stainless-steel body for enhanced durability and anti-vibration performance. The series is certified to meet international safety standards, offering high-pressure resistance up to 4.9 MPa and low heat transfer loss, which contributes to improved energy efficiency.

A key design feature is Sanhua’s patented bi-metal joints, which combine stainless steel pipes with pure copper terminals to simplify brazing during installation and maintenance. The SHF-G series is suitable for ambient temperatures from -30°C to +50°C and supports various mounting configurations, including coil-upward or horizontal-axis installation.

The valves are available with multiple coil options, covering both AC and DC power supplies, and a range of connection types to accommodate different system requirements.
