Emerson Alco 049189 Solenoid Valve

The Emerson Alco 049189 Solenoid Valve (model 200RB5T5M) is a heavy-duty, 2-way normally closed solenoid valve engineered for precise refrigerant flow control in commercial refrigeration and HVAC systems. As a pilot-operated valve, it utilizes a 5/8" ODF sweat connection with extended copper ends, allowing technicians to braze the unit into the liquid, suction, or discharge line without disassembling the internal components. This model is distinguished by its integrated manual stem, providing a critical manual override for system evacuation, charging, or emergency troubleshooting when electrical power is unavailable.

Designed for versatile performance, this refrigerant solenoid valve delivers a nominal R22 capacity of 8.2 tons and an R134a capacity of 6.2 tons at standard rating conditions. The 200RB series features a PTFE O-ring for a superior external seal and is compatible with a wide range of refrigerants, including R-404A, R-407C, and R-410A. With a Maximum Operating Pressure Differential (MOPD) of 300 psig and a maximum working pressure of 500 psig, this Alco solenoid valve ensures reliable liquid line shut-off and prevents refrigerant migration during the off-cycle.

• Manual Override Capability: The manual stem allows for physical opening of the valve during service or power failures.
• Simplified Installation: Extended sweat ends protect internal seals from heat damage during brazing, saving time on the job site.
• Universal Coil Compatibility: Designed to work with the Emerson AMC coil family, allowing one coil size to fit the entire 200RB valve range.
• High Thermal Resilience: Rated for fluid temperatures up to 250°F, making it suitable for demanding hot gas bypass or discharge line applications.
• Serviceable Design: Field-repairable construction with available solenoid valve repair kits to extend the life of the valve body.

• Does this valve include the solenoid coil? No, this is a "Valve Less Coil" (VLC) model. You must pair it with the appropriate Emerson solenoid coil based on your system's voltage requirements.
• Can this valve be used for bi-directional flow? Standard 200RB valves are uni-directional. However, they can be converted for bi-flow operation using a specific internal component kit, except for the larger 7, 9, and 12 port sizes.
• What is the proper mounting orientation? For optimal performance, it is recommended to mount the valve with the solenoid coil in a vertical upright position. Mounting more than 90 degrees off-vertical is not advised.
