Danfoss 068Z3405 Valve
The Danfoss 068Z3405 (TES2) is a high-performance thermostatic expansion valve engineered for precise refrigerant injection into evaporators. Designed specifically for R404A / R507 systems, this valve utilizes an external equalization connection (1/4 in. flare) to compensate for pressure drops across the evaporator, ensuring optimal superheat control. The 3/8" x 1/2" flare connections allow for straightforward installation and field replacement in commercial refrigeration units, walk-in coolers, and ice machines. This valve features a stainless steel power element laser-welded for longevity and a balanced port design (when used with the appropriate orifice) to prevent flash gas issues and maintain stability across varying head pressures. The adjustable superheat setting allows technicians to fine-tune the system for specific load conditions, protecting the compressor from liquid slugging while maximizing heat transfer efficiency in the evaporator coil.
Key Benefits for Contractors- Precise Superheat Control: External equalization effectively manages pressure drops to prevent evaporator starvation.
- Durable Construction: Stainless steel capillary tube and bulb resist corrosion and vibration fatigue in demanding environments.
- Interchangeable Orifice Assembly: The modular design permits easy capacity adjustments without removing the valve body from the line.
- Wide Temperature Range: Optimized for low and medium temperature applications common in food preservation and cold storage.
- Reliable Sealing: High-grade flare connections minimize the risk of refrigerant leaks compared to low-quality alternatives.
What is the benefit of external equalization on the TES2?
External equalization is critical when using a distributor or when the evaporator pressure drop exceeds 2 PSI. It ensures the valve senses the true pressure at the evaporator outlet, providing accurate superheat control.
Can this valve be used with refrigerants other than R404A?
The 068Z3405 is specifically charged for R404A and R507. Using it with different refrigerants will result in incorrect superheat tracking and potential system failure due to the pressure-temperature curve mismatch.
Where should the sensing bulb be mounted?
For best results, mount the bulb on a horizontal section of the suction line at the 4 o'clock or 8 o'clock position. Ensure it is properly insulated and located before the external equalization tap.
