Danfoss 067N9412 TXV
The Danfoss 067N9412 TGEX-15 is a high-capacity R-22 thermostatic expansion valve engineered for precision refrigerant metering in air conditioning and heat pump systems. Rated for 15 tons, this TXV valve features a 7/8" ODF inlet and a 1 1/8" ODF outlet, utilizing a balanced port design to maintain stable superheat control across varying head pressures. This unit is an exact technical replacement for the HFES15HC 7/8x1 1/8, ensuring a seamless drop-in fit for contractors servicing legacy R-22 equipment. The TGEX-15 thermal expansion valve includes a laser-welded stainless steel power element for enhanced durability and a reliable Danfoss expansion valve bulb charge that responds rapidly to load changes. Designed for bimetal soldering, the copper connections allow for fast installation without the need for extensive heat sinking, making it a preferred choice for field replacements where reliability and precise HVAC superheat adjustment are critical for system longevity.
Key Benefits for Contractors
- Direct Interchangeability: Functions as a high-performance equivalent to the HFES15HC, simplifying inventory and field selection.
- Balanced Port Design: Minimizes the influence of varying condensing pressures on mass flow, ensuring consistent evaporator feeding.
- Internal and External Equalization: Optimized for systems with high pressure drops across the evaporator to maintain efficiency.
- Bimetal Connections: Facilitates easy brazing of the 7/8" x 1 1/8" ODF ports without damaging the internal valve components.
- Wide Operating Range: Specifically calibrated for R-22 refrigeration systems, handling high-tonnage demands up to 15 tons accurately.
Common Installation Questions
Is the Danfoss 067N9412 compatible with modern refrigerants?
This specific model is calibrated for R-22 systems. Using it with different refrigerants will result in improper superheat settings and potential compressor damage due to differing pressure-temperature curves.
What is the proper orientation for the TGEX-15 bulb?
For 7/8" or larger suction lines, the bulb should be mounted at the 4 o'clock or 8 o'clock position on a horizontal run to avoid reading oil return temperatures rather than true vapor temperature.
Can I use this TXV for heat pump applications?
Yes, the Danfoss TGEX series is designed with a bypass function capability or can be used in bi-flow configurations if specified by the system mechanical design.
