The Danfoss 137X4067 is a high-performance thermostatic expansion valve (TXV) engineered for precise refrigerant flow control in commercial air conditioning, refrigeration and heat pump systems. Designed by Danfoss, a global leader in HVAC and refrigeration technology, this valve helps maintain optimal evaporator performance while improving overall system efficiency.
As part of the Danfoss expansion valve range, the 137X4067 provides accurate superheat regulation, helping to maximise cooling capacity while protecting compressors from liquid refrigerant return. Its robust brass construction and balanced port design deliver reliable operation under varying load and pressure conditions.
Configured for R407C refrigerant applications, the Danfoss 137X4067 features external equalisation, adjustable superheat settings and a durable thermostatic element. This makes it an excellent choice for air conditioning units, commercial refrigeration equipment, chillers and heat pump installations requiring dependable refrigerant control.
Thermostatic expansion valves regulate the flow of liquid refrigerant entering the evaporator by monitoring superheat at the evaporator outlet. This ensures efficient heat transfer, improved cooling performance and protection against compressor damage caused by liquid refrigerant carryover.
The Danfoss 137X4067 combines proven thermostatic control technology with robust mechanical construction, making it suitable for demanding commercial HVAC and refrigeration applications where reliability and efficiency are critical.
