Emerson Alco 061675 Expansion Valve

The Emerson Alco 061675 (model TER 35 HW) is a high-capacity thermal expansion valve engineered for heavy-duty commercial HVAC and industrial refrigeration systems utilizing R22 refrigerant. Rated for 35 tons of nominal capacity, this TXV features a medium temperature charge (HC code), making it ideal for standard air conditioning and medium-temp chiller applications. Technicians will find the 10-foot capillary tube length provides necessary flexibility for remote bulb placement on large suction lines, ensuring precise superheat control and evaporator efficiency. This specific configuration is supplied as a valve less flange, allowing for customization and reuse of existing refrigeration flange assemblies in retrofit or repair scenarios. The external equalizer design compensates for pressure drops across the coil, a critical requirement for maintaining optimal system performance in high-tonnage circuits.

• Optimized Superheat Control: The HC power assembly charge prevents hunting and maintains steady evaporator pressure across variable load conditions.
• Interchangeable Flange Design: Provides field flexibility, allowing for easier serviceability without replacing the entire liquid line connection.
• Extended Reach: Includes 10' of capillary tubing for professional routing and secure bulb strapping on large-diameter piping.
• Durable Construction: Built by Emerson Alco to resist corrosion and withstand the mechanical vibrations common in large-scale commercial rooftop units.

What is the primary application for the Emerson TER 35 HW?
This valve is designed for high-tonnage R22 systems, typically found in commercial air conditioning or process cooling, requiring accurate liquid refrigerant metering at medium suction temperatures.

Can this valve be used with other refrigerants?
The 061675 is specifically calibrated for R22. Utilizing different refrigerants will result in incorrect superheat settings and potential compressor damage due to floodback or starvation.

Is the flange included with this model?
No, this is a less flange model. It is designed to be installed using a separate Emerson flange kit compatible with your specific line size requirements.
