THERMO EXPANSION VALVE ΤΙ-MW FOR R134a/R413A ALCO

ALCO TI series of Thermo
-Expansion Valves with interchangeable orifices are designed for refrigeration applications such as display cases in supermarkets, walkin/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 0.4 to 14,2 kW based on R404A
• 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 equaliser
• Inlet brazing adapter
• Adjustable static superheat

Thermo
-Expansion Valves control the superheat of refrigerant vapour at the outlet of the evaporator. They act as a throttle device between the high and low pressure sides of refrigeration system and ensures the rate of refrigerant flow into the evaporator exactly matches the rate of evaporation of liquid refrigerant. Thus the evaporator is fully utilised and no liquid refrigerant may reach the compressor.

When the actual superheat is higher than the set point, Thermo
-Expansion Valve feeds the evaporator with more liquid refrigerant. Likewise, the valve decreases the refrigerant flow to the evaporator when the actual superheat is lower than the set point.
