Emerson Alco 059076 Expansion Valve

The Emerson Alco 059076 is a professional-grade TCLE 10 HW100 thermostatic expansion valve engineered for precision refrigerant metering in high-capacity systems. Designed specifically for R22 refrigerant applications, this 10-ton externally equalized TXV features a medium temperature charge, making it an ideal solution for commercial refrigeration and air conditioning maintenance. The "Take-Apart" design of the Alco T-Series allows for superior field serviceability, enabling technicians to replace the cage, flange, or power assembly independently without removing the entire valve body. This model includes a 5-foot SAE external capillary tube and a stainless steel power assembly to resist corrosion and ensure consistent superheat control across varying loads. For contractors handling R-22 system repairs, the Emerson 059076 provides the reliability needed for 10-ton evaporators requiring external equalization to compensate for pressure drops.

• Enhanced System Stability: The externally equalized design accurately monitors evaporator outlet pressure, preventing compressor slugging and evaporator starving.
• Field Serviceable Construction: Part of the "Take-Apart" T-series, allowing for modular component replacement and simplified cleaning of the TXV cage assembly.
• Corrosion Resistance: Features a high-grade stainless steel power assembly that withstands harsh mechanical environments and prevents premature failure.
• Precise Superheat Adjustment: Equipped with an external adjustment screw for fine-tuning the refrigerant flow to meet specific application requirements.
• Optimized Medium Temp Charge: Specifically calibrated for medium temperature ranges, ensuring efficient heat transfer and cycle performance for R22.

Is the flange included with this model?
No, the Emerson Alco 059076 is sold as the valve body and power assembly only (TXV less flange). You must utilize your existing flange or purchase a compatible T-series flange for installation.

Can this valve be used with refrigerants other than R22?
This specific HW100 power element is charged and calibrated for R22 systems. Using it with different refrigerants will result in improper superheat and potential system damage.

Where should the external equalizer line be connected?
The 1/4" SAE external equalizer line should be connected to the suction line immediately downstream of the sensing bulb to ensure the valve responds to the actual pressure at the evaporator outlet.
