Sanhua International SHF(L)-7H-34 Rev Valve 3/8 Inch Tube Esc 1/2 Inch

The Sanhua International SHF(L)-7H-34 Reversing Valve is a four-way refrigerant flow control valve used in heat pump systems to switch the direction of refrigerant flow between heating and cooling modes in HVAC systems. It operates by redirecting refrigerant through the systems coils, allowing the same equipment to provide both heating and cooling operations depending on operating conditions. It is installed in compatible heat pump and air conditioning assemblies during servicing or replacement procedures where it connects to the refrigerant circuit using a 3/8-inch tube connection and 1/2-inch ESC port configuration for controlled flow routing.
