Emerson Alco 060855 Expansion Valve Els PW 17895 these are specifically sized forThe Emerson Alco 060855, specifically the TJLE 11 HC, is a high capacity thermal expansion valve (TXV) designed for precise refrigerant metering in large scale commercial AC and refrigeration systems. Engineered for R22 refrigerant, this 11 ton valve utilizes a medium temperature charge to maintain optimal superheat across varying load conditions. The externally equalized design compensates for pressure drops across the evaporator, ensuring efficient
