Danfoss Thermostatic Expansion Valve (T2)

The Danfoss 068Z3346 Thermostatic Expansion Valve is a precision-engineered T2 (TN2) thermostatic expansion valve (TXV) designed for efficient refrigerant control in R134a and R513A refrigeration and HVAC systems. It regulates the flow of liquid refrigerant into the evaporator based on superheat, ensuring optimum performance, improved energy efficiency, and reliable operation under varying load conditions. The valve features an angleway, internally equalized design and a long capillary bulb to accurately sense evaporator temperature and modulate refrigerant flow accordingly.

Constructed with a brass body and brass flare connections (3/8? inlet × 1/2? outlet), this valve is suitable for medium- and low-temperature systems including commercial coolers, transport refrigeration, supermarket display cases, and other cooling applications. Its adjustable superheat setting and wide operating temperature range of approximately –40 °F to +50 °F (–40 °C to +10 °C) offer flexible performance across various environments.
