Thermal Expansion Valves The LA(E) series is a desuperheating (Liquid Injection) valve used in conjunction with hot gas bypass to prevent excessive suction line superheat. LA(E) valves can be used for interstage cooling in compound systems. Stainless steel power element eliminates corrosion and prevents valve failure May operate at superheat settings in excess of 20°F allowing the valve to perform in desuperheating applications External superheat adjustment SAE or ODF connections External or internal equalizer Wrench flats on inlets and outlets (SAE only) Replaceable inlet strainer (SAE only) • Maximum working pressure: 500 psig Nomenclature example: LAES 2 CL 5 FT 3/8 x 1/2 ODF S/T LA Valve Series De-Superheating Liquid Injection Connection Type Capacity NOTE: This is not system capacity Refrigerant Code Charge Code Capillary Tube Length Inlet x Outlet Connection Sizes (See tables below) S = solder (Omit for flare) (Contact Application Engineering for sizing) (See hot gas bypass charts for valve selection) Connection Type Configuration ODF=solder SAE=flare External Equalizer Fitting Socket Depth Connection Size Inlet Outlet Connection Size Inlet Emerson Climate Technologies
