Emerson Alco 057317 Expansion Valve

The Emerson Alco 057317 is a high-capacity balanced ported expansion valve engineered for precision refrigerant metering in commercial air conditioning and refrigeration systems. Specifically designed for 15-ton R22 and R407C applications, this externally equalized thermal expansion valve (TXV) effectively compensates for pressure drops across the evaporator, ensuring consistent superheat control and maximizing coil efficiency. This model features a 5/8" x 7/8" ODF sweat connection in a straight-through body configuration, facilitating a clean inline installation for contractors.

The HFES 15 HC 5FT is equipped with a stainless steel replaceable power element, which provides superior resistance to corrosion and prevents premature diaphragm failure in harsh environments. With its medium temperature charge and a 5-foot capillary tube, this valve is optimized for stable performance during variable head pressure or partial load conditions. It is an essential component for technicians looking to maintain HVAC system reliability and prevent liquid slugging in large-scale cooling equipment.

• Refined Refrigerant Metering: The balanced port design maintains precise flow control despite fluctuations in head pressure.
• Corrosion Resistance: High-grade stainless steel power assembly ensures long-term durability in demanding field conditions.
• Dual Refrigerant Compatibility: Field-ready for both R22 and R407C systems, providing flexibility for legacy repairs and retrofits.
• Optimized Coil Performance: External equalization allows for accurate evaporator superheat management across a 15-ton capacity range.

• Can this valve be used for heat pump applications? This specific HFES 15 HC model is designed with a medium temperature charge; while the HF series supports bi-flow in smaller sizes, always verify your specific system flow requirements for 15-ton configurations.
• How do I handle the 5-foot capillary tube during installation? Ensure the capillary tube is supported at the power element when unrolling and avoid sharp bends to prevent work hardening and potential leaks.
• What is the benefit of the ODF sweat connections? The solder connections provide a leak-proof, permanent seal suited for high-vibration commercial environments.
