Emerson Alco 047515 Solenoid Valve

The Emerson Alco 047515, specifically the 200RB4S4T solenoid valve, is a pilot-operated, 2-way normally closed valve designed for high-performance refrigeration and air conditioning systems. Engineered for reliability, this refrigeration solenoid valve body features a 1/2" ODF sweat inlet and a 5/8" ODM sweat outlet, ensuring a secure fit in standard liquid, suction, or discharge lines. With a nominal R22 cooling capacity of 8.0 tons and an R134a capacity of 6.0 tons, it is suitable for medium to large commercial applications. The pilot operated design allows for operation with a minimum pressure drop, while the integrated mounting stud simplifies installation on heavy-duty bracketry. This Alco 200RB series valve is compatible with various refrigerants, provided you match the pressure ratings and flow requirements of the specific system. When replacing HVAC solenoid valves, ensure the coil voltage matches the existing controls to maintain proper cycling and avoid premature field failure.

• High Flow Capacity: Rated for 8.0 tons on R22 and 6.0 tons on R134a, making it ideal for commercial rack systems and large split units.
• Durable Construction: The 200RB4S4T features a robust brass body and extended copper connections to facilitate brazing without overheating internal components.
• Mounting Stability: Includes a factory-installed mounting stud to reduce vibration stress on the piping.
• Normally Closed Logic: Provides fail-safe shutoff in the event of power loss to the coil.

What is the difference between ODF and ODM connections on this valve?
The 1/2" ODF (Outside Diameter Female) connection accepts 1/2" tubing inside the fitting, while the 5/8" ODM (Outside Diameter Male) connection is designed to fit into a 5/8" ODF fitting or coupling.

Does this valve body include the electrical coil?
No, this is the valve body only. You must select the appropriate AMG or ASC2 series coil based on your system's voltage requirements (e.g., 24V, 120V, or 240V).

Can this 200RB valve be mounted in any orientation?
For optimal performance and to prevent debris accumulation on the diaphragm, it is recommended to mount the valve with the coil in a vertical upright position.
