The Danfoss T2 and TE2 thermostatic expansion valves are two of the most popular components in the HVAC refrigeration industry. Rigorous certification has been completed for three A2L ultra-low GWP refrigerants: R454C, R455A and R1234yf:
The Danfoss T2/TE2 expansion valve is used in environmentally friendly refrigerant systems
  Danfoss is committed to the development and design of environmentally friendly and energy-efficient products, and wants to help equipment manufacturers and installers accelerate the pace of system upgrades. In addition to the T2 and TE2 thermostatic expansion valves, we will also accelerate the attainment of ASHRAE A2L safety ratings for other components to meet the growing demand for low GWP refrigerant solutions, such as R404A and R134a refrigerant alternatives.

Since the introduction of the T2 expansion valve in 1966, Danfoss has always believed that the product design must be based on the needs of the user and continuously optimize the product according to the relevant characteristics of the refrigerant.

Danfoss products are validated to meet international standards, and like most ultra-low GWP environmentally friendly refrigerants, R454C, R455A and R1234yf are micro-flammable refrigerants (ASHRAE rated A2L safe) and must be used in conjunction with other safety specifications.

Optimization and upgrade of expansion valves:

Compatibility testing between new refrigerants and lubricants

Thermostat Optimization – Adjust the opening of the expansion valve according to the temperature change of the thermostat

"With the increasing popularity of new generation refrigerants, designers of refrigeration and air conditioning systems have been committed to the research and development of new refrigerant conversion technologies in recent years. Regardless of the future, Danfoss will continue to leverage its expertise in energy-saving technologies and product development to provide customers with more safe, reliable and energy-efficient products and solutions. Ejner Kobbero, Director of Product Development for Expansion Valves at Danfoss, said.
