Emerson Alco 037049 Cage Assembly

The Emerson Alco 037049 (Model X22440B8B) is a high-performance cage assembly designed for TCL and TCLE series take-apart thermostatic expansion valves. Engineered for versatility in commercial refrigeration and HVAC systems, this TXV cage features a bi-flow capability, making it suitable for heat pump applications and systems requiring bidirectional refrigerant flow. It is built to maintain stable superheat control even under varying load conditions, supporting system efficiency from full load down to 10% capacity.

This interchangeable cage assembly is compatible with multiple refrigerants, providing nominal capacities of 12 tons for R22 and R407C, 9 tons for R134a, and 8 tons for R404A, R507, and R502. Designed for field serviceability, the take-apart construction allows for rapid internal component replacement without de-brazing the valve body from the line. It supports a maximum working pressure of 450 psig. Professional installation requires a torque of 60-64 inch-pounds for the cage and 300 lb-in for the flange bolts to ensure a leak-proof seal.

Key Benefits:

• Multi-Refrigerant Compatibility: Optimized for R22, R134a, R407C, and R404A systems.
• Field Serviceable Design: The take-apart architecture enables fast cage replacement, reducing system downtime.
• Bi-Flow Performance: Ideal for heat pumps and diverse HVACR configurations requiring flexible flow directions.
• Precision Metering: Delivers consistent superheat control across a wide range of operating pressures.
• Heavy-Duty Construction: Built to withstand commercial refrigeration demands with a 450 psig pressure rating.

Common Questions:

Is this cage assembly compatible with TRAE+ series valves?
No, the 037049 X22440B8B is specifically designed for TCL and TCLE valve bodies. Always verify the valve series prefix before attempting installation.

Can I use this for an R410A system?
This specific model is rated for R22, R134a, R407C, and R404A. For R410A applications, a different cage assembly designed for higher operating pressures is required.

Does the assembly include the required gaskets?
Standard Emerson Alco cage assemblies typically include the necessary seating gaskets, but it is best practice to have a T-series gasket kit on hand for a complete seal during field service.
