Danfoss 067N9403 Expansion Valve
The Danfoss 067N9403 is a high-performance TGEX 10 thermal expansion valve engineered for precision refrigerant metering in commercial air conditioning and heat pump systems. Featuring a 60-inch capillary tube and a straight body design, this externally equalized TXV is optimized for R22 and R407C applications with a 6-ton capacity. The 1/2" ODF inlet and 5/8" ODF outlet connections utilize copper bimetal connectors for rapid, safe brazing without the need for intensive heat-sinking. Built with a stainless steel power element and a laser-welded diaphragm, the 067N9403 ensures stable superheat control across its operating range. Designed with a Maximum Operating Pressure (MOP) of 667 PSI, it protects the compressor motor against excessive suction pressure during start-up or after defrost cycles. This valve includes a number 6 orifice and bulb strap, providing a reliable solution for technicians requiring field-proven durability and exact HVAC refrigerant flow control.
Key Benefits for Technicians:
- Optimized Superheat Stability: The TGEX 10 series provides consistent liquid injection into the evaporator, preventing liquid slugging and improving system COP.
- Efficient Installation: Features 1/2" x 5/8" ODF solder connections that allow for direct brazing into the line set without disassembly.
- Built-in System Protection: The 667 PSI MOP charge limits the suction pressure, preventing motor overloads in high-load scenarios.
- Extended Reach: The 5-foot (60") capillary tube offers flexibility for bulb placement on larger evaporator manifolds.
- Dual Refrigerant Compatibility: Specifically calibrated for R22 and R407C, making it a versatile choice for retrofits and legacy repairs.
Common Questions:
What is the benefit of the external equalization on the Danfoss 067N9403?
External equalization is critical for systems with significant pressure drops across the evaporator or distributor. It ensures the valve senses the true pressure at the evaporator outlet, maintaining precise superheat regardless of internal friction losses.
Can this Danfoss TGEX valve be used in heat pump applications?
Yes, the 067N9403 is designed for both air conditioning and heat pump duty, featuring a balanced port construction to handle varying load conditions effectively.
Is the orifice replaceable in this specific model?
This unit comes with a fixed number 6 orifice pre-installed, optimized for the 6-ton capacity rating to ensure reliable performance without the leak risks associated with interchangeable orifice assemblies.
