Danfoss 068Z3414 Expansion Valve

The Danfoss 068Z3414 is a TS2 thermostatic expansion valve designed for precise refrigerant flow control in small-to-medium scale cooling systems. Engineered for high performance with R404A and R507, this flare TXV features an internal equalization design, eliminating the need for an external pressure line. The 1.5-meter capillary tube provides flexibility for various evaporator configurations, while the 3/8-inch inlet ensures a secure, leak-resistant connection. For technicians handling low-temperature refrigeration or commercial food storage applications, this valve offers a reliable superheat adjustment range, maintaining optimal evaporator efficiency even under fluctuating thermal loads. The stainless steel power element is laser-welded for longevity, ensuring the diaphragm maintains its charge integrity against common mechanical fatigue. By optimizing system pressure drop and liquid injection, this valve prevents liquid slugging and evaporator starve, making it a staple for maintaining high COP (Coefficient of Performance) in rigorous HVACR environments.

• Interchangeable Orifice System: Allows for field customization of cooling capacity without replacing the entire TXV body.
• Internal Equalization: Simplifies piping and reduces potential leak points in standard refrigeration cycles.
• Wide Temperature Range: Specifically calibrated for N-range or B-range applications to handle demanding evaporating temperatures.
• Field-Serviceable Design: The superheat setting can be fine-tuned via the adjustment spindle to meet specific site requirements.
• Durability: Stainless steel construction protects against corrosion and provides superior strength at the flare connection points.

What refrigerant types is the Danfoss TS2 compatible with?
This specific model is optimized for R404A and R507, ensuring the charge in the thermal bulb matches the pressure-temperature curve of these refrigerants for accurate control.

Does this expansion valve include the orifice?
Standard Danfoss TS2 bodies are typically sold without the orifice. Ensure you select the correct orifice assembly size based on your specific BTU/hr system requirements.

How do I adjust the superheat on this valve?
The valve features a manual adjustment spindle. One full turn typically changes the static superheat by approximately 4K (7.2°F), allowing for precise HVAC system tuning.
