Danfoss 068Z3415 Valve

The Danfoss 068Z3415 Valve is a professional-grade TES 2 thermostatic expansion valve designed for precise liquid injection into evaporators. Engineered for compatibility with R404A and R507 refrigerants, this valve features an externally equalized design via a 1/4" solder connection, ensuring accurate superheat control even in systems with significant pressure drops. The physical configuration includes a 3/8" flare inlet and a 1/2" solder (ODF) outlet in an angleway body style, facilitating clean piping layouts in tight mechanical spaces. With a 5-foot (1500mm) capillary tube and a stainless steel power element, the 068Z3415 is built to withstand a maximum working pressure of 500 psig. It operates within a wide temperature range of -40°F to +50°F, making it a reliable choice for low and medium-temperature refrigeration. This TXV utilizes the interchangeable orifice assembly system, allowing for flexible capacity matching across various evaporator loads while maintaining a stable superheat setting. Professionals value the laser-welded diaphragm, which enhances reliability under high-cycle conditions.

• Precise Superheat Control: The external equalization compensates for evaporator pressure drops, preventing hunting and protecting the compressor.
• Durable Construction: Features a brass valve body and a stainless steel capillary tube and bulb for long-term corrosion resistance in harsh environments.
• Flexible Installation: The 3/8 x 1/2 angleway design and interchangeable orifice system allow for easy field retrofits and capacity adjustments.
• Wide Operating Envelope: Optimized for R404A/R507 systems operating between -40°F and +50°F.

• Does this valve include the internal orifice? No, the Danfoss 068Z3415 is the valve body and power element only; the orifice assembly must be selected separately based on your required tonnage.
• Where should the sensing bulb be mounted? For optimal performance, mount the bulb on a horizontal section of the suction line at the 4 o'clock or 8 o'clock position, upstream of the external equalization line.
• What is the maximum pressure rating? This TES 2 expansion valve is rated for a Maximum Working Pressure (MWP) of 500 psig (34 bar).
