Emerson Alco 049163 Solenoid Valve

Standardize your refrigeration and air conditioning systems with the Emerson Alco 049163 Solenoid Valve, a high-performance 2-way normally closed pilot-operated component. Engineered for liquid line, suction gas, and discharge gas service, this 200RB4T4T model features 1/2 inch ODF sweat extended ends, allowing for rapid brazing without dismantling the internal valve assembly. As the direct replacement for 047518, it includes a pre-installed mounting stud for secure installation in high-vibration commercial environments.

This pilot operated refrigeration solenoid valve is optimized for high-capacity systems, delivering a nominal liquid capacity of 8.0 tons for R22 and 6.0 tons for R134a. Built to handle a maximum working pressure of 680 psig and fluid temperatures up to 250°F, its PTFE O-ring and long-life molded coil compatibility ensure a superior external seal and consistent magnetic actuation. The 200RB series modularity means one coil fits all valve sizes, streamlining your truck stock and reducing downtime during field repairs.

• Universal Coil Compatibility: Uses standard ASC2 or AMG coils, allowing a single coil type to service multiple valve bodies in the 200RB line.
• Direct Retrofit: Seamlessly replaces the legacy 047518 model, including the essential mounting stud for immediate bolt-on application.
• Brazing Efficiency: Extended copper ends dissipate heat effectively, protecting internal seats and seals during the sweat connection process.
• Multi-Refrigerant Support: Rated for use with R22, R134a, R404A, R507, and other common A1 class refrigerants.
• Superior Sealing: Features a high-grade PTFE O-ring to prevent external leaks and resist chemical degradation from oil and refrigerant mixtures.

• Is this valve compatible with R410A systems? Yes, the 200RB4T4T is rated for a maximum working pressure of 680 psig, making it suitable for modern high-pressure R410A applications.
• Does this unit include the solenoid coil? No, this is a Valve Less Coil (VLC) body. You must pair it with a compatible Emerson ASC2, DM, or AM series coil based on your system voltage requirements.
• Can I use this for bi-flow heat pump applications? While the standard 049163 is a directional valve, it can be converted for bi-flow operation using a KS30293 kit, though factory-assembled bi-flow versions are typically preferred for new installs.
