HF/HFK Series Thermal Expansion Valves The HF series is a balanced ported valve designed for refrigeration, air conditioning and heat pump applications. • Stainless steel replaceable power element eliminates corrosion and prevents valve failure • Two body sizes provide capacities from 1/4 to 20 tons • The HF is offered several ways: – Pre-packaged HFK service kits – Include a mix of bodies and power elements with a complete set of cages to serve the most applications with a minimum of parts – Individual components – Bodies, cages, & power elements may be ordered separately – Finished valves – Assembled valves ready for immediate installation • Bi-Flow capability up to 5-1/2 tons R-22 allows one valve to control the superheat in both cooling and heating modes NOTE: If the HF body is stamped HFK, then the cage is replaceable. ODF or SAE connections Straight-through or angle flow configurations Removable inlet strainer (ODF only) Internal or external equalizer • Maximum working pressure: • UR/CUR file number: • Capacity range from 8 to 20 tons (R-22) • Finished valve only Nomenclature example: HFESC 2 HC 5 FT 3/8 x 1/2 ODF S/T HF Valve Series Superheat Equalizer Connection Removable Bleed Capacity Adjustment Type Inlet Strainer Hole Nominal N = Non- E=External S = Solder (optional) (optional) Rating in Balanced Adjustable Tons Port (Omit for (Omit for C = Inlet Design Omit for Internal) SAE Flare) Strainer (Omit for (See nominal Adjustable (ODF only) no bleed capacity hole) table below) Refrigerant Charge Code Capillary Inlet x Outlet Connection Configuration Code Tube Connection Type +F = R-12 C = medium temp Length Sizes ANG = 90° angle • H = R-22 CA = heat pump SAE = flare S/T = straight-thru +M = R-134a W(MOP) = press. 5 FT (std) 1/4 x 3/8 ODF = solder • N = R-407C limiting 3/8 x 1/2 * P = R-507 Z = low temp * R = R-502 AA = wide range * S = R-404A + = 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 HF Series-Nominal* Capacity Tables in Tons (kW) Standard Body HF 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.

HF/HFK Series Thermal Expansion Valves Ordering Information HFK Pre-Packaged Kits The HFK is a pre-packaged kit consisting of a mix of popular bodies and power elements with a complete selection of cages. These kits provide great flexibility allowing valves to be assembled as needed for each application. Three kits are provided as shown below, along with the cage kit which is included in each pre-packaged kit. In addition, custom kits can be assembled by stocking an empty kit case with desired components. Insertion Tool HFK Assembly Procedure (see 6 assembly steps & diagrams below) 1. Remove...
