Emerson Alco 058490 Expansion Valve
The Emerson Alco 058490 is a high-capacity, balanced port thermal expansion valve specifically engineered for large-scale heat pump and air conditioning systems. This HFES series valve (Model HFES 20 HCA 5FT 7/8 x 1 1/8 ODF S/T) provides 20 tons of nominal capacity, making it a critical component for maintaining precise superheat control in R22 expansion valve and R407C refrigeration systems. Designed with a stainless steel replaceable power element, it effectively prevents valve failure due to corrosion while ensuring stable bi-directional flow performance in diverse operating conditions.
Featuring a straight-through body with 7/8" x 1 1/8" ODF sweat connections, this externally equalized TXV is built for seamless integration into high-demand residential or commercial setups. The 5-foot capillary tube allows for flexible bulb placement to optimize evaporator efficiency. As a direct EBSVE20-GA replacement, this unit offers a reliable solution for technicians looking to restore system equilibrium. Professionals should always check pipe size compatibility before installation to avoid erratic refrigerant metering and ensure peak thermodynamic stability.
Key Benefits- Enhanced Stability: The balanced port design compensates for varying pressure drops, providing consistent superheat control across a wide range of evaporator loads.
- Corrosion Resistance: Equipped with a stainless steel power assembly to extend the service life of the metering device in harsh environments.
- Versatile Application: Optimized for heat pump charge configurations, supporting both cooling and heating cycles with high-precision regulation.
- Standardized Connections: Features ODF solder connections and an external equalizer to integrate easily into existing 20-ton HVACR circuits.
- Simplified Maintenance: The straight-body configuration and standard 5' capillary length facilitate straightforward field replacement and diagnostic access.
Is the 058490 compatible with both R22 and R407C?
Yes, this valve is designed for R22/R407C capacity. When retrofitting R22 systems to R407C, ensure the superheat is adjusted to account for the different pressure-temperature characteristics of the refrigerant blend.
What is the primary difference between this and the EBSVE20-GA?
The 058490 is the designated replacement for the EBSVE20-GA. However, you must verify the physical pipe diameters (7/8" inlet and 1 1/8" outlet) as some older EBS series valves may have utilized different connection specifications.
Why is external equalization necessary for a 20-ton valve?
In high-capacity systems, the pressure drop across the evaporator is often significant. An externally equalized thermal expansion valve senses pressure at the evaporator outlet, ensuring the valve responds to the true superheat rather than the pressure at the valve outlet.
