Emerson Alco 043205 Solenoid Valve

The Emerson Alco 043205 (Model 240RA9T7T) is a heavy-duty, 2-way normally closed solenoid valve designed for high-capacity refrigeration and air conditioning systems. Engineered for versatile performance, this diaphragm refrigeration solenoid valve is compatible with a wide range of refrigerants, offering a nominal R22 capacity of 30.5 tons and an R134a capacity of 28.9 tons. This 7/8" sweat ODF connection valve features extended copper ends, allowing for direct brazing into the line without the need for disassembly, which protects internal components and streamlines field installation. Its PTFE diaphragm is reinforced with woven fiberglass, providing enhanced durability in hot gas service, liquid, or suction line applications. With a Maximum Operating Pressure Differential (MOPD) of 300 psig and a maximum working pressure of 500 psig, this valve is a reliable choice for commercial contractors managing large-scale industrial cooling loads.

• Optimized Performance: Specifically designed for high-tonnage R22 and R134a systems, ensuring efficient flow control in industrial refrigeration environments.
• Field Flexibility: Includes a mounting stud for secure installation; compatible with standard Emerson AM, ASC2, and DM coils (sold separately).
• Rugged Construction: The normally closed 2-way valve design ensures fail-safe operation, while the 9/16" port size minimizes pressure drop across the system.
• High-Temperature Resilience: The integrated fiberglass-reinforced PTFE diaphragm is rated for fluid temperatures up to 250°F, ideal for discharge gas applications.

• Can this valve be used for hot gas bypass? Yes, the Emerson 240RA series is specifically rated for hot gas service due to its high-temperature diaphragm construction.
• Does the valve come with the coil? This is a Valve Less Coil (VLC) body. You must pair it with a compatible Emerson solenoid coil based on your specific voltage requirements.
• Is disassembly required before brazing? No, the extended solder ends allow you to braze the 7/8" connections without dismantling the internal diaphragm or seat assembly.
