Copeland Comfort Control (Alco) 068292 TXV

The Copeland Comfort Control (Alco) 068292 TXV (Model: TER 26 HW 10FT 7/8ODF 1 1/8ODM SAE S/T) is a high-capacity thermostatic expansion valve designed for precision refrigerant metering in large-scale commercial air conditioning and industrial cooling systems. Engineered for systems utilizing R22 or R407C refrigerant, this valve provides a nominal 26-ton capacity, making it a critical component for maintaining evaporator efficiency in high-load applications. The straight body configuration features 7/8" ODF inlet and 1 1/8" ODM outlet connections, ensuring a robust fit for standard copper piping. For superior system protection, this model includes an MOP (Maximum Operating Pressure) charge, which limits evaporator pressure to prevent compressor motor overload during high-load startups or defrost cycles.

This externally equalized TXV utilizes a 1/4" SAE flare connection to compensate for pressure drops across the evaporator and distributor, ensuring accurate superheat control. The 10' capillary tube offers significant flexibility for bulb placement on larger suction lines. As part of the T-Series Take-Apart line, the Copeland Comfort Control (Alco) 068292 allows for field-serviceable component replacement, including the power assembly and cage, reducing downtime for contractors during maintenance. The adjustable superheat stem allows for fine-tuning based on specific HVACR system requirements to prevent liquid slugging and optimize coil performance.

Key Benefits for Technicians:

• Large Cooling Capacity: Rated for 26-ton capacity, ideal for commercial chillers, rooftops, and large-unit replacements.
• MOP Charge Protection: Integrated Maximum Operating Pressure charge protects the compressor by limiting suction pressure during heavy pull-down.
• System Compatibility: Versatile design approved for use with both R22 and R407C refrigerants.
• Precision Metering: Externally equalized design (1/4" SAE) ensures stable superheat even in systems with high pressure drops.
• Serviceable Design: Modular Take-Apart construction permits the replacement of individual components without de-brazing the entire valve body.

Common Questions:

Is the Alco TER 26 HW compatible with R407C retrofits?
Yes. This valve is specifically designed for the pressure-temperature characteristics of both R22 and R407C, making it a reliable choice for 407C conversion projects where high capacity is required.

When should I use the external equalizer on the Copeland Comfort Control (Alco) 068292?
Always connect the 1/4" external equalizer line to the suction line after the bulb. This is mandatory for 26-ton systems or any setup using a refrigerant distributor to account for the internal pressure drop and ensure the valve maintains the correct superheat.

What is the benefit of the 10-foot capillary tube?
The extended 10' capillary tube is essential for large commercial units where the distance between the valve body and the optimal sensing bulb location on the suction header is greater than standard lengths allow.
