Copeland Comfort Control (Alco) 070738 Cage Assembly

The Copeland Comfort Control (Alco) 070738 Cage Assembly, identified by the technical crossover model X9166B10B, is a high-capacity double ported cage assembly designed for TIR valve systems. This balanced-ported component is engineered for modern large-scale refrigeration and HVAC applications, offering bi-flow operation and external adjustability. It provides precise refrigerant metering and stable control across a wide range of pressures, making it essential for heavy-duty commercial refrigeration circuits.

The 070738 cage supports multiple refrigerants with specific nominal capacities, including 55 tons for R22 and R407C, 45 tons for R134a, and 37 tons for R404A, R502, and R528. Its dual-port design allows the valve to remain balanced against high pressure drops, ensuring consistent performance in high-tonnage evaporators and condenser applications where traditional single-port cages often struggle with hunting or seat erosion.

Technical Benefits

• High-Capacity Versatility: Direct replacement for X9166B10B, supporting systems up to 55 tons depending on the refrigerant type.
• Balanced-Port Design: Minimizes the effects of fluctuating head pressures, providing stable superheat control in bi-flow configurations.
• Broad Compatibility: Validated for use with R-22, R-134a, R-404A, R-407C, and R-502, allowing for standardizing inventory across various job sites.
• Externally Adjustable: Facilitates field tuning to optimize system efficiency without breaking the refrigerant circuit.

Common Questions

Is the 070738 cage assembly compatible with bi-flow heat pump applications?
Yes, the balanced-ported design of the TIR valve type assembly allows for efficient operation in both flow directions, which is standard for high-tonnage heat pump and refrigeration systems.

What is the difference between the 070738 and the X9166B10B?
These two part numbers refer to the same Alco cage assembly. The 070738 is the primary Copeland identification number used for replacement parts ordering.

Does this cage assembly require a specific power assembly?
This cage must be used with the appropriate TIR series valve body and power assembly matched to the specific refrigerant and tonnage requirements of your system.
