BA/BN Series Thermal Expansion Valves The BA/BN series is a balanced ported valve. Typical applications include: refrigerated cases, coolers, freezers, ice machines and air conditioning systems. BA/BN valves operate over widely varying operating conditions. Stainless steel power element eliminates corrosion and prevents valve failure Hermetic, leak-free construction Compact size allows installation in limited spaces Bi-Flow capability allows one valve to control the superheat in both cooling and heating modes for heat pump applications Balanced port construction compensates for changes in operating pressures due to varying ambients, gas defrost, heat reclaim, or widely varying evaporator loads • Maximum working pressure: 700 psig ZW195 charge available for R-410A systems External or internal equalizer Bleed type pressure equalization available to accommodate PSC type compressors SAE or ODF connections standard – Chatleff or Aeroquip are available Adjustable or non-adjustable superheat Nomenclature example: BAEB 1/2 HCA 5 FT 3/8 x 1/2 ODF S/T B Valve Series Superheat Adjustment A = Adjustable Bleed Hole (optional) Capacity Nominal Rating in Tons Charge Code Capillary Tube Length Inlet x Outlet Connection Sizes Connection Type Hermetic Balanced Port Design (Omit for no bleed hole) (See nominal capacity table below) C = medium temp CA = heat pump W(MOP) = press. limiting Z = low temp + = 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 BA/BN 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 Emerson Climate Technologies

BA/BN Series Thermal Expansion Valves Ordering Information 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 R-12 valve. 2004FC-118 R13 (01/14) Emerson Climate...
