Emerson Alco 063416 Power Assembly

The Emerson Alco 063416 is a high-precision TF-Series Power Assembly engineered for demanding R22 refrigeration and air conditioning systems. This assembly features the X-28458 HW100-2 design, specifically utilized in TRAE+ Series Thermal Expansion Valves. Built with a stainless steel power element, it provides exceptional corrosion resistance and mechanical durability, ensuring stable superheat control even under fluctuating head pressures. The 1/4 inch Flare External Equalizer allows the valve to compensate for pressure drops across the evaporator, which is critical for maintaining system efficiency in large-tonnage applications.

A standout technical feature is the MOP 100 PSI Charge (Maximum Operating Pressure), which prevents motor overload by limiting the suction pressure during heavy startup loads or high-temperature pull-downs. The 10-foot capillary tube offers significant installation flexibility for remote sensing bulb placement. Designed for professionals, this replacement expansion valve power head ensures seamless HVACR valve maintenance by allowing the power element to be swapped without removing the entire valve body from the line, minimizing downtime during critical repairs.

Key Benefits:

• MOP 100 PSI Pressure Limiting: Protects the compressor motor from excessive suction pressure during high-load conditions.
• Corrosion-Resistant Diaphragm: The stainless steel construction prevents premature failure and ensures long-term operational stability.
• External Equalizer Connection: Features a 1/4" flare connection for accurate sensing of evaporator outlet pressure.
• Extended Reach: Includes a 10' capillary tube to accommodate complex piping layouts and optimal bulb positioning.
• Field Serviceable: Designed as a direct replacement for Alco TRAE+ valves, facilitating rapid component upgrades.

Common Questions:

What is the purpose of the MOP 100 PSI charge on this power assembly?
The HW100 MOP charge acts as a safety limit by preventing the thermostatic expansion valve from opening further once the suction pressure reaches 100 PSI. This prevents the compressor from drawing too much current during a hot pull-down, effectively protecting the motor.

Is the 063416 compatible with refrigerants other than R22?
This specific model is calibrated exclusively for R22 refrigerant systems. Using it with different refrigerants will result in incorrect superheat settings and potential liquid slugging or poor evaporator utilization.

Does this assembly include the cage or the valve body?
No, the 063416 is a replacement power assembly only. It is designed to be threaded onto an existing Emerson Alco TRAE+ series valve body during routine HVAC repair or maintenance.
