Emerson Alco 060855 Expansion Valve

The Emerson Alco 060855, specifically the TJLE 11 HC, is a high-capacity thermal expansion valve (TXV) designed for precise refrigerant metering in large-scale commercial AC and refrigeration systems. Engineered for R22 refrigerant, this 11-ton valve utilizes a medium temperature charge to maintain optimal superheat across varying load conditions. The externally equalized design compensates for pressure drops across the evaporator, ensuring efficient coil utilization and preventing liquid floodback to the compressor. This model features a 5-foot capillary tube with SAE external connections for flexible installation in tight mechanical headers. Built with the rugged T-series take-apart construction, it allows for internal component inspection or replacement without de-brazing the entire assembly. For contractors handling HVAC system repair or R22 expansion valve replacement, the TJLE series remains a standard for reliability and mechanical precision in industrial refrigeration applications.

• Interchangeable Components: The take-apart design facilitates easy maintenance and orifice sizing adjustments without removing the valve body from the line.
• Stable Superheat Control: The HC charge is specifically tuned for medium temperature applications, reducing hunting and improving system efficiency.
• External Equalization: Critical for high-tonnage systems to ensure accurate sensing of evaporator outlet pressure.
• Durable Construction: Stainless steel power assembly resists corrosion and ensures long-term HVACR part reliability in demanding environments.
• Application Versatility: Ideal for commercial HVAC maintenance where R22 systems require precise liquid line metering.

Does this valve include the flange?
No, this is a "TXV less flange" model. You must use your existing flange or purchase the appropriate bolt-on flange kit separately for installation.

Can I use this TXV on a system with a large pressure drop across the evaporator?
Yes, because this is an externally equalized expansion valve, it monitors pressure at the evaporator outlet, making it the correct choice for systems with distributors or high-pressure drop coils.

Is the 5-foot capillary tube long enough for remote bulb placement?
In most 11-ton configurations, the 5' capillary tube length provides sufficient reach to mount the sensing bulb on the suction line at the 4 o'clock or 8 o'clock position for accurate thermal feedback.
