Copeland Comfort Control (Alco) 088837 Cage Assembly

The Copeland Comfort Control (Alco) 088837 Cage Assembly, also identified by part number X-11873-B4B, is a heavy-duty, take-apart internal component designed for T-Series Thermo Expansion Valves. Built for high-capacity industrial and commercial refrigeration, this TJR valve type cage assembly handles significant thermal loads across a broad range of medium and low-temperature applications. It offers precise superheat control and is essential for maintaining system balancing when swapping or servicing HVAC expansion valve parts without disturbing piping. With a 3100 kPa (450 psi) safe working pressure, it is bi-flow compatible when paired with the appropriate power element, making it a versatile choice for heat pump reversals. This modular TXV cage replacement ensures that technicians can match specific tonnage requirements across multiple refrigerants, including R-22, R134a, and R407C, providing a high-reliability solution for Copeland T-series expansion valves.

• Multi-Refrigerant Versatility: Specifically engineered for nominal capacity ratings of 8 tons (R-12), 11 tons (R134a), 14 tons (R-22/R407C), and 9 tons (R404A/R502/R521).
• Serviceable Design: The two-bolt take-apart configuration allows for rapid TXV orifice assembly replacement or cleaning without breaking line connections.
• Bi-Flow Capability: Optimized for use in heat pump expansion valves when integrated with HCA-charged power elements.
• Precision Metering: Delivers stable superheat regulation even under wide load variations or fluctuating head pressures.

• Is the 088837 compatible with older Alco T-Series bodies? Yes, the 088837 is the standardized replacement cage for the X11873B4B and fits all standard TJR-style valve bodies.
• Does this cage assembly include gaskets? Standard T-Series cage assemblies typically come with the necessary gaskets; however, using a new X13455-1 gasket kit is recommended for a leak-free seal.
• What tools are needed for installation? A standard torque wrench is required to tighten the body flange cap screws to the manufacturer-specified 35 Nm to avoid body distortion.
