Emerson Flow Control (Alco) 057410 Thermostatic Expansion Valve 3/8x1/2 ODF Angle 1-Ton R22

The Emerson Flow Control (Alco) 057410 is a high-performance thermostatic expansion valve (TXV) engineered for precision refrigerant control in residential and commercial HVAC systems. Part of the HFESC series, this externally equalized valve is specifically designed for R22 refrigerant applications with a capacity rating of 1 ton.

Key Features:

• Balanced port design for stable operation and optimal superheat control
• 3/8" x 1/2" ODF (Flare) angle connections for easy installation
• External equalizer design monitors evaporator pressure for precise refrigerant flow regulation
• Stainless steel replaceable power assembly eliminates corrosion and extends service life
• Maximum working pressure of 450 psig (31 bar)
• Compatible with air conditioning, refrigeration, and heat pump systems

This externally equalized valve requires an external sensing bulb to accurately monitor evaporator conditions, ensuring consistent superheat control and optimal system efficiency. The angle body configuration is ideal for installations where space constraints or piping layouts require a 90-degree flow pattern. The balanced port design provides stable performance across varying load conditions, while the modular construction allows for field service of individual components.
