Emerson is pleased to announce the launch of the new thermal expansion valve TA, which is designed for multiple low capacity commercial refrigeration applications including showcase, coldroom, ice making machine, refrigerated truck and so on.

The Key features of TA as below:
• Compatible with R22, R134a and R404a
• Capacity range: 0.82 to 19.8 kW @ R22
• Stable and accurate superheat control over wide load and evaporating temperature range • Easy and precise static superheat adjustment
• High consistency of whole cycle
• 8 exchangeable orifices cover board capacity range and give flexibility of selection
• Cleanable inlet strainer, convenient for field maintains
• Internal or external equalizer available
• Flare or brazing outlet connections available
• Stainless-steel capillary and tube give excellent durability and avoid galvanic corrosion

Model Range : 

The TCL(E) Take-Apart valves, with adjustable superheat and replaceable, interchangeable components are ideal for original equipment and field replacements in air conditioning, heat pump, and refrigeration applications.

• Take-Apart construction for easy field service
• External superheat adjustment
• B-Flow Capability
• Stainless steel power assembly up to 18 tons
• 1/4 to 12 tons nominal capacity

Model Range : 

The A-series is used for heat pump, air conditioning, food services and commercial applications.

• Stainless steel power element eliminates corrosion and prevents valve failure
• Hermetic, leak-free construction
• Compact size allows installation in limited spaces
• Mass spectrometer tested to ensure less than 0.10 oz/year external leakage rate

Model Range : 

TRAES series hermetic thermal expansion valve is a compact designed product. The TRAES valve provides an ideal superheat control solution to the small-medium size chillers, heat pumps, and water heating applications.

• Compact hermetic design.
• Balanced port design compensate for changes in evaporator temperature or widely varying evaportaor loads to assure accurate control and reliable operation
• Stainless power element
• Superheat adjustable
• Staright-through configuration and ODF connection

Model Range : 

Today’s systems require improved energy effi ciency, tighter temperature control and the incorporation of new features, such as remote monitoring and diagnostics. An electronic control solution can provide the optimal performance to meet these needs. Emerson is leading the industry with its revolutionary bi-polar stepper motor driven control valve for commercial air conditioning and refrigeration applications. The patented EX series electrical control valves, featuring the fastest response time in the industry, meet or exceed today’s most demanding application requirement for long lasting reliable and precise control of refrigerant fl ow. Complementing the valves is our EC series network-enabled electronic valve drivers and superheat controllers. For the complete cutting edge technology solution, choose Emerson.

Model Range : 

The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm.

Application :- Chiller , Heat Pump, Cold Room, Ultra Low Temperature System. 

Their is some type of Expension Valve which is mentioned below. 

1). Thermostic Expension Valve 
2). Electronic Expension Valve
