Emerson Alco 061673 Expansion Valve

The Emerson Alco 061673, specifically the TER 22 HC thermal expansion valve, is a high-capacity 22-ton R22 TXV designed for precise refrigerant metering in medium-temperature applications. Engineered for large-scale systems, this take-apart expansion valve features a 10-foot capillary tube and a balanced port construction that compensates for varying pressure drops across the evaporator, ensuring stable superheat control even under fluctuating load conditions. This model is provided less flange, allowing technicians to utilize existing mechanical connections or select specific flange kits for custom installations. The medium temperature charge is optimized to prevent compressor flooding while maintaining maximum evaporator efficiency in commercial HVAC and refrigeration systems.

• Enhanced Capacity Control: The 22-ton rating provides the necessary flow for large commercial evaporators without hunting.
• Modular Design: The take-apart style allows for easy cleaning, power assembly replacement, or internal component inspection without brazing.
• Superior Response: The 10' capillary length offers flexibility in sensing bulb placement to ensure accurate suction line feedback.
• R22 Compatibility: Specifically calibrated for HCFC-22 systems requiring a reliable, mechanical metering device.

Is the power assembly replaceable on the TER 22 HC?
Yes, the TER series utilizes a modular design, allowing the power element to be swapped if the charge is lost, minimizing system downtime.

Does this valve include the inlet and outlet flanges?
No, the 061673 is sold less flange. You must retain your existing hardware or purchase the appropriate flange kit for your line size.

What is the primary application for the medium temperature charge?
This charge is specifically tuned for suction temperatures typically found in walk-in coolers and standard air conditioning applications to prevent liquid slugging during startup.
