1PC NEW Danfoss expansion valve TX2-068Z3206-R22/R407C free shipping. The two refrigerants have similar thermal properties, making them compatible with this expansion valve. Direct Supply BRAND NEW PARTS Applicable refrigerants : R22 (traditional Freon refrigerant) and R407C (non-azeotropic blend refrigerant, an environmentally friendly alternative to R22). The two refrigerants have similar thermal properties, making them compatible with this expansion valve. Temperature range : The evaporation temperature is typically -40℃ to 10℃, covering medium and low-temperature refrigeration needs, suitable for equipment such as air conditioners and refrigerators. Maximum working pressure : 34bar (approximately 500psig), capable of withstanding pressure loads on the high-pressure side of the refrigeration system to ensure stable operation. Interface specifications : Connection type: Flare connection, which is easy to install with reliable sealing performance, suitable for on-site quick assembly. Inlet size: Commonly 3/8 inch (about 9.5mm); outlet size is mostly 1/2 inch (about 12.7mm), subject to the official technical manual for details. Capillary length : Approximately 1500mm (59 inches), used to transmit the temperature signal of refrigerant at the evaporator outlet via the sensing bulb, enabling dynamic flow regulation. Superheat control : Static superheat is approximately 4℃ (7.2℉). The sensing bulb detects changes in superheat and automatically adjusts the valve opening to ensure efficient heat exchange in the evaporator, preventing liquid carryover in return gas or excessive superheat. Pressure balancing method : Internal balancing, suitable for systems with small evaporator pressure losses (such as small air conditioners and commercial refrigerators), simplifying system design. Valve body material : Brass, featuring good corrosion resistance and thermal stability, compatible with the chemical properties of refrigerants like R22 and R407C, and capable of long-term stable operation in conventional refrigeration environments. Application scenarios : Small and medium-sized commercial air conditioners, supermarket refrigerators, display cabinets, heat pumps, and other refrigeration equipment. It acts as a throttling component to control the flow of refrigerant into the evaporator, maintaining stable system operation and ensuring refrigeration efficiency.
