Emerson Alco 062725 Expansion Valve

The Emerson Alco 062725 Thermal Expansion Valve is a heavy-duty, large-capacity solution engineered specifically for high-demand refrigeration, air conditioning, and heat pump applications. This TRAE+ 20 HCA model features a double balanced port design, which is critical for maintaining stable superheat control across wide load variations and fluctuating evaporator temperatures. It is compatible with R22 and R407C refrigerants and provides a nominal 20-ton capacity. The straight-through body configuration with 7/8" x 1 1/8" ODF sweat connections ensures a solid, leak-resistant installation for professional mechanical contractors.

Designed for longevity in the field, this valve utilizes a stainless steel power element to resist corrosion and a large diaphragm for superior operating stability. The externally equalized setup and 10-foot capillary tube allow for versatile placement in complex piping layouts. As part of the TRAE Plus series, the 062725 is fully serviceable, featuring a replaceable cage assembly (compatible with Emerson cage kit 063389) and a replaceable power element, allowing technicians to perform maintenance without removing the entire valve body from the line. The "HCA" charge is specifically optimized for heat pump performance, ensuring reliable refrigerant metering during both heating and cooling cycles.

• Double Balanced Port Technology: Prevents hunting and provides precise superheat control even during low ambient or high head pressure conditions.
• Enhanced Serviceability: Features a replaceable cage assembly and power element, significantly reducing downtime and labor costs during repairs.
• Field-Adjustable Superheat: External adjustment allows for fine-tuning system performance to meet specific job site requirements.
• Rugged Construction: Equipped with solid copper connections and a permanent inlet strainer to protect the internal orifice from debris.
• Bi-Flow Capability: Engineered to handle the demands of modern heat pump systems using R22 or R407C.

Is the 062725 suitable for R410A systems?
No, this specific model is designed for R22 and R407C applications. Using it with R410A will lead to incorrect metering due to the pressure differences and the thermostatic charge in the bulb.

What is the purpose of the 10-foot capillary tube?
The extended 10' capillary length provides the flexibility needed to mount the sensing bulb in the optimal location on large-diameter suction lines, especially in high-tonnage commercial chillers and rooftop units.

Does this valve include the internal check valve?
The TRAE+ series typically utilizes a double balanced port to handle variations, but always verify your specific system piping if a separate check valve is required for bypass flow in heat pump reverse cycles.
