EMERSON TI series of Thermo™-Expansion Valves with interchangeable orifices are designed for refrigeration applications such as display cases in supermarkets, walk-in/reach-in coolers, freezers, soft ice cream/ice maker machines, milk tank coolers, transport refrigeration as well as for air conditioning and heat pump systems. TI provides flexibility in selection of capacity and is ideal for those applications requiring compact size with stable and accurate control over wide load and evaporating range.
Features
• Eight interchangeable orifice assemblies provide a capacity range from 0.5…19.4 kW based on R448A
• 45 bar maximum working pressure allows the use of high pressure refrigerants
• Three styles of connections:
- TILE: Stainless steel brazed fittings eliminate the need of wet rags during brazing
- TIS(E): Copper brazed fittings (valve requires wet rag during brazing)
- TI(E): Flare
• Cleanable / exchangeable inlet strainer in orifice assembly
• Constant superheat across a wide application range
• Large diaphragm eliminates disturbances to the valve and provides smoother and consistent valve control
• Laser welded stainless steel power element
• Internal or external equalizer
• Inlet brazing adapter
• Adjustable static superheat
• Special setting upon request an minimum 100 pieces order quantity
