Emerson Alco 061674 Expansion Valve

The Emerson Alco 061674 TER26HC is a high-performance R22 expansion valve engineered for precision refrigerant metering in intensive air conditioning and heat pump applications. Featuring take-apart construction, this T-series component allows for efficient field service, enabling technicians to access internal components without de-brazing the entire assembly. As a thermostatic expansion valve, the TER26HC utilizes an external superheat adjustment to maintain optimal evaporator efficiency, effectively preventing liquid slugging and ensuring the compressor remains protected. The 061674 model is supplied less flange, providing contractors with the flexibility to match specific refrigeration system requirements using interchangeable body flanges. It features a 10-foot capillary tube for versatile bulb placement and a stainless steel power assembly that resists corrosion in harsh environments. With a maximum working pressure of 450 psig, this valve is a reliable choice for maintaining precise superheat control in R22 systems, delivering consistent HVAC system performance across varying load conditions.

• Serviceable Design: Take-apart construction simplifies maintenance and internal component replacement in the field.
• Precise Metering: External superheat adjustment allows for fine-tuning to maximize evaporator heat transfer efficiency.
• Durable Components: The stainless steel power assembly ensures long-term reliability and resistance to environmental wear.
• System Flexibility: Being sold less flange and part of a modular series, it supports diverse configurations for multi-tonnage applications.
• Operational Stability: Designed to prevent refrigerant overfeed, which helps eliminate evaporator icing and maintains cooling capacity.

What is the primary function of the TER26HC expansion valve?
The Emerson Alco 061674 acts as a precision regulator, monitoring the refrigerant temperature at the evaporator outlet and adjusting the flow to the inlet to maintain a constant superheat, ensuring the evaporator is fully utilized.

Can this valve be used for bi-flow applications?
Yes, the TER series expansion valves are designed with bi-flow capability, making them ideal for heat pump systems where refrigerant flow directions change between heating and cooling cycles.

What refrigerant is the 061674 compatible with?
This specific model is calibrated for R22 refrigerant systems. Using it with other refrigerants may lead to inaccurate superheat settings and potential system inefficiency.
