Emerson Alco 064103 Expansion Valve

Ensure precise refrigerant metering with the Emerson Alco 064103 Thermal Expansion Valve, a veteran-grade solution for residential and light commercial HVACR systems. This AACE-Series model is designed for high-performance 5-ton expansion valve applications, offering compatibility with R22 and R407C refrigerants. Built with a stainless steel power element to prevent corrosion and a hermetic, leak-free construction, this valve provides exceptional durability in demanding environments. Featuring 3/8" x 1/2" ODF sweat connections and a 30-inch capillary tube, it includes an internal check valve for seamless reverse flow in heat pump cycles, eliminating the need for external piping. The externally equalized design and wide range charge (HAA) provide superior superheat stability across varying load conditions. Whether you are performing a TXV replacement or a new installation, this straight-body Emerson AACE 5 HAA valve ensures accurate flow control and critical compressor protection by preventing liquid slugging.

• Internal Check Valve: Optimizes heat pump performance by allowing reverse flow without additional external components.
• Wide Range Charge: Specialized HAA charge enhances superheat stability for R22/R407C capacity across high and low load demands.
• Compact Footprint: Engineered for easy installation in tight evaporator cabinets and confined mechanical spaces.
• Corrosion Resistance: The stainless steel power element ensures longevity and prevents premature valve failure.
• Precision Metering: Delivers accurate refrigerant flow to maximize evaporator efficiency and system SEER ratings.

• What is the primary benefit of the internal check valve? It allows the valve to function in heat pump applications by permitting reverse flow during the heating cycle, which simplifies piping and reduces leak points.
• Is this valve compatible with modern R22 alternatives? Yes, this external equalizer expansion valve is technically characterized for both R22 and R407C, making it a versatile choice for retrofits.
• Why use an externally equalized TXV for a 5-ton system? External equalization compensates for pressure drops across the evaporator, ensuring the superheat is accurately maintained for larger capacity 5-ton coils.
