AFA(E) Series Thermal Expansion Valves The AFA series is designed for air conditioning and commercial refrigeration applications requiring angle configuration SAE connections. The AFA is ideal for those applications requiring compact size combined with stable and accurate control over wide load and evaporator temperature ranges. Stainless steel power element eliminates corrosion and prevents valve failure External superheat adjustment Replaceable inlet strainer SAE connections only Wrench flats on inlet and outlet External or internal equalizer • Maximum working pressure: • UR/CUR file number: Nomenclature example: AFAE 1/2 HC 5 FT 3/8 x 1/2 SAE ANG AF Valve Series Hermetic Design, Flare Connections Superheat Adjustment A = Adjustable Equalizer E=External (Omit for Internal) Capacity Nominal Rating in Tons (See nominal capacity table below) Charge Code C = medium temp CA = heat pump W(MOP) = press. limiting Z = low temp AA = wide range Capillary Tube Inlet x Outlet Connection Length Connection Sizes Type 30 IN & 1/4 x 3/8 SAE=flare 5 FT (std) 3/8 x 1/2 + = R-12 and R-134a are interchangeable refrigerant charges, * = R-507, R-502 and R-404A are interchangeable refrigerant charges, • = R-22 and R-407C are interchangeable refrigerant charges AFA Series – Nominal* Capacity Table in Tons (kW) R-12 – All capacities shown are at 100°F condensing, 40°F evaporator temperature. *See Extended Capacity Tables for ratings at a wide range of conditions per ARI standard 750.

AFA(E) Series Thermal Expansion Valves Ordering Information Internally Equalized Refrigerant Externally Equalized Refrigerant * For interchangeable refrigerant charges R-134a/R-12, R-404A/R-507/R-502, and R-22/R-407C, the tons of capacity shown in the table are for the first (primary) refrigerant listed. Consult the Nominal Capacity Table for determining the tons of capacity for the secondary refrigerants listed. Example: A 1/4 ton R-12 valve is required. What R-134a ton valve should be selected? Solution: From the Nominal Capacity Table, a 1/2 ton R-134a valve is equivalent to a 1/4 ton...
