Emerson Alco 062437 TXV Power Head

The Emerson Alco 062437 TXV Power Head, model XB-1019HW100-1B, is a high-performance replacement power assembly designed for T-series thermostatic expansion valves. This component is engineered for precise refrigerant metering in air conditioning and heat pump applications, specifically utilizing R-22, R-407C, and R-407A. Featuring a 5-foot capillary tube and a 1/4" SAE pressure connection, it provides the mechanical force necessary to modulate the valve orifice based on evaporator load. The large diaphragm design ensures stable control and minimizes hunting, even during high-pressure fluctuations. Built with corrosion-resistant materials, this HVAC expansion valve part is the industry standard for maintaining superheat stability in commercial and residential systems. For technicians performing field service, this modular power head allows for easy element replacement without removing the entire valve body from the line, significantly reducing downtime and labor costs during refrigerant flow control repairs.

• Precise Superheat Control: The large diaphragm creates superior closing force for stable evaporator coil performance.
• Multi-Refrigerant Compatibility: Optimally charged for R-22, R-407C, and R-407A systems.
• Durable Construction: Stainless steel high-strength diaphragm resists fatigue and environmental corrosion.
• Field Serviceability: Modular T-series design allows for quick power element swaps to restore system functionality.
• Extended Reach: Includes a 5-foot capillary tube for flexible sensing bulb placement on the suction line.

Is the XB-1019HW100-1B compatible with R-410A systems?
No, this specific power head is charged for R-22 and its common retrofits (R-407C/A). Using it with R-410A will result in incorrect superheat settings and potential compressor damage due to pressure rating differences.

Does this power assembly include the cage and body?
This is the power head assembly (element) only. It is designed to be threaded onto an existing Alco T-series valve body.

Can this be used on heat pump systems with biflow requirements?
Yes, when paired with the appropriate T-series valve body, this power head supports biflow applications common in heat pump reversing cycles.
