Emerson Alco 044846 Valve

The Emerson Alco 044846 (Model X6346-17) is a heavy-duty, take-apart expansion valve body designed for high-demand HVACR systems. Engineered for use with the TCL and TCLE series, this valve body features a 5/8" ODF sweat inlet and a 7/8" ODF sweat outlet, facilitating a robust straight-thru body flow configuration. As part of Alco’s legendary T-Series, it offers maximum flexibility for technicians, allowing for the easy replacement of internal cages, power assemblies, and flanges without needing to de-braze the entire unit from the line.

Built with a durable brass construction and designed to withstand a maximum working pressure of 450 psig, this valve body is a reliable solution for air conditioning, heat pump, and commercial refrigeration applications. The ODF solder connections ensure a leak-proof seal, while the take-apart design drastically reduces downtime during field service and capacity adjustments. Whether you are performing a field replacement or a new installation, the X6346-17 provides the precision and durability required for professional-grade refrigerant metering.

• Modular Tank-Apart Design: Simplifies field service by allowing internal components to be swapped without removing the valve body from the system.
• Straight-Thru Flow: Optimizes piping layout for thermal expansion valve installations where space and pressure drop are critical factors.
• Versatile Compatibility: Designed specifically for Alco TCLE series and TCL series components, ensuring a precise fit with standard cages and power elements.
• Rugged Construction: High-grade brass body capable of handling standard refrigerants like R-22, R-404A, and R-407C when paired with the appropriate internals.
• Contractor Preferred: Features standard 5/8 x 7/8 ODF sizing to match common liquid and suction line requirements.

• Is this compatible with R-410A systems? The X-series body is generally rated for 450 psig; always verify that your specific power assembly and cage are rated for R-410A pressures before installation.
• Does this include the internal orifice or cage? This part number is the valve body only. Cages and power assemblies must be selected based on your specific tonnage and refrigerant requirements.
• Can this be used for bi-flow applications? When used with the correct T-series internal components, these bodies are capable of bi-flow operation in heat pump cycles.
