Emerson Alco 041566 Cage Assembly

For veteran technicians servicing high-capacity systems, the Emerson Alco 041566 (Model X22517B7B) is the industry-standard replacement cage assembly designed for the versatile TL-Series and T-Series take-apart thermal expansion valves. This OEM component is engineered for precise refrigerant metering and stable superheat control across a range of applications. The X22517B7B cage features a robust internal construction to withstand high head pressures and varying load demands, ensuring the evaporator receives the exact mass flow required for optimal heat exchange. Whether you are performing a field teardown on a commercial chiller or a rooftop package unit, this TXV cage kit allows for rapid capacity adjustment without removing the entire valve body from the line. Its multi-refrigerant compatibility makes it a critical stock item for maintaining systems running on older R12/R502 or modern R134a and R407C blends.

• High Pressure Durability: Rated for high-pressure refrigerants and compatible with systems utilizing XB power elements up to 46 bar.
• Broad Compatibility: Supports a wide range of refrigerants including R22, R404A, and R134a for maximum inventory flexibility.

Is the X22517B7B compatible with balanced port valves?
This cage is designed for the standard T-Series and TL-Series take-apart bodies. For balanced port applications such as the TJR series, ensure the flange and power assembly match the balanced port requirements for proper stroke and alignment.

What is the torque specification for the flange bolts when installing this cage?
When reassembling the take-apart valve, ensure the flange bolts are tightened in a secondary pattern to approximately 300 lb-in (34 Nm) to ensure a leak-free seal on the gaskets.

How do I verify if this 10-ton cage is the correct fit for my system?
Check the existing cage for the X22517B7B stamping or consult the Emerson capacity charts based on your specific evaporator temperature and pressure drop across the valve.
