Liebert 178157P2S Expansion Valve 321042-401 If the magnetic field isThe Liebert 178157P2S Expansion Valve is a critical OEM 6 ton thermostatic expansion valve (TXV) engineered for high capacity precision cooling in commercial and industrial HVACR environments. Designed to maintain optimal superheat settings between 10 and 15F, this valve ensures efficient liquid refrigerant metering into the evaporator coil. By precisely regulating flow, it prevents liquid slugging to the scroll compressor and maximizes heat exchange
