Application & Benefits
The Danfoss TGEN series TXVs are trusted by HVAC/R professionals for their consistent superheat regulation and durable construction. The external equalizer design makes this valve ideal for evaporators with multi-circuit distributors or longer refrigerant circuits where evaporator pressure drop is a factor. The 60″ capillary tube provides installation flexibility, allowing the sensing bulb to be positioned precisely on the suction line for optimal system performance. The included bulb strap ensures a secure, thermally conductive connection between the sensing bulb and the suction line.
The MOP rating of 667 PSI provides a built-in safety limit that protects the compressor from overload during high-load startup conditions, making this valve well suited for commercial refrigeration and medium-temperature applications using R134a.
