068Z3421 - Thermostatic expansion valve, TE 2, R404A/R507A Danfoss

Product details Danfoss TE 2 Thermostatic Expansion Valve | R404A/R507A | Flare/Solder Product Description: The Danfoss TE 2 expansion valve is a cornerstone of reliable refrigeration, specifically calibrated for R404A and R507A refrigerants. This valve is widely used in the UAE for commercial refrigeration applications, such as walk-in cold rooms and supermarket display cases, where precise superheat control is essential for protecting the compressor. The TE 2 features a replaceable orifice assembly, making it highly versatile and easy to service in the field. Its stainless steel power element and robust design ensure a long service life, even in the high-ambient temperatures and demanding conditions of Dubai’s industrial cooling sectors. Key Features & Benefits: Precise Superheat Control: Automatically adjusts refrigerant flow to maximize evaporator efficiency and prevent liquid slugging. Interchangeable Orifice: Allows for easy capacity adjustments and simplified maintenance for UAE service technicians. Stainless Steel Power Element: Provides superior strength and corrosion resistance, essential for longevity in humid environments. Versatile Application: Specifically optimized for R404A/R507A, the standard refrigerants for many commercial freezing projects in Dubai. Proven Reliability: A globally recognized design trusted by HVAC/R professionals for decades.   Technical Specifications : Specifications Value Manufacturer Danfoss Product Model TE 2 Code Number 068Z3421 Refrigerant(s) R404A / R507A Inlet Connection 3/8 in Flare Outlet Connection 1/2 in Flare Equalization Type External (1/4 in Flare) Max. Working Pressure 34.0 bar   FAQs: Q: Does this valve include the orifice? A: Usually, the TE 2 body (068Z3421) is sold separately from the orifice. Ensure you select the correct orifice size for your specific capacity in the UAE. Q: Why use external equalization in a Dubai project? A: External equalization is necessary for systems with a significant pressure drop across the evaporator, ensuring accurate superheat sensing. Q: Can I use this valve with R134a? A: No, this specific model is charged and calibrated only for R404A/R507A. Using it with other refrigerants will result in poor performance.   View More View Less
