Emerson Alco 047508 Solenoid Valve

The Emerson Alco 047508 is a high-performance 200RB4F3T solenoid valve engineered for precision refrigerant control in commercial systems. As a pilot-operated refrigeration solenoid valve, this 2-way normally closed component is designed for liquid, suction, or discharge gas service. This specific model features 3/8" flare connections (SAE) and a built-in mounting stud for simplified installation on the bracket or panel. Built for versatility, the Emerson 200RB series features extended ends and a PTFE O-ring for superior external sealing, ensuring reliable operation even under high-pressure conditions up to a 500 PSIG maximum working pressure.

Rated for an 8.0 Ton capacity on R22 and a 6.0 Ton capacity on R134a, the 200RB4F3T-VLC is compatible with most modern A1, A2L, and A3 class refrigerants, including R404A and R507. Technicians should note that this is a Valve Less Coil (VLC) body; it requires a standard Emerson ASC or AMG series solenoid coil for operation. Its pilot-operated design ensures a low minimum pressure drop of 2 PSI, making it an efficient choice for large-scale refrigeration and HVACR racks.

• Enhanced Sealing: Equipped with a PTFE O-ring to provide a reliable external seal and prevent refrigerant leaks in high-vibration environments.
• Universal Compatibility: The Emerson 200RB series utilizes a single-coil family across all valve sizes, reducing the inventory required for maintenance calls.
• Robust Construction: Features extended flare ends to facilitate easier wrench access and a mounting stud for a secure, professional finish.
• High Thermal Range: Designed to handle a maximum fluid temperature of 250°F, making it suitable for hot gas discharge applications.

• Is the coil included with the 047508 valve body? No, this is a Valve Less Coil (VLC) assembly. You must select the appropriate voltage coil (e.g., 24V, 120V, or 240V) separately to complete the installation.
• Can this valve be mounted in any orientation? For optimal performance, the 200RB4F3T should be mounted with the coil in a vertical-up position. Mounting more than 90° off-vertical is not recommended as it may affect the pilot operation.
• What is the MOPD for this refrigeration solenoid? This valve features a Maximum Operating Pressure Differential (MOPD) of 300 PSIG when used with standard AC coils.
