Copeland Comfort Control (Alco) 047503 Solenoid Valve

The Copeland Comfort Control (Alco) 047503 Solenoid Valve is a direct-acting refrigeration solenoid valve engineered for precision liquid or discharge gas service. This 2-way normally closed (NC) body is a heavy-duty solution for refrigerant flow control in residential and commercial systems, featuring the 100RB2S2 design architecture. Built with 1/4" sweat (ODF) connections and extended ends, it allows for straightforward brazing without the risk of internal seal damage. Supporting a maximum working pressure (MWP) of 500 psig and a maximum operating pressure differential (MOPD) of 300 psig, this valve is optimized for R22 and R134a applications, with nominal liquid capacities of 1.27 tons and 1.20 tons respectively. It serves as a direct technical replacement for the 032F7105, provided a new compatible coil is used to match system voltage requirements. The internal PTFE O-ring ensures superior external sealing and high-temperature tolerance up to 250°F.

Key Benefits for Contractors

• Universal Compatibility: The 100RB series utilizes a standardized coil design that fits all valve sizes, simplifying truck stock and field replacements.
• High Pressure Resilience: Rated for a 500# maximum pressure, making it suitable for modern high-pressure refrigerant environments.
• Leakproof Integrity: Features a durable leakproof body joint and high-grade PTFE sealing to prevent refrigerant loss and maintain system vacuum.
• Installation Efficiency: 1/4" sweat connections with extended ends facilitate fast installation in both vertical and horizontal orientations.
• Direct OEM Replacement: Replaces 032F7105 and is compatible with 100RB2S2 VLC configurations for reliable system restores.

Common Questions

Is the solenoid coil included with this valve body?
No, the 047503 is a Valve Less Coil (VLC) model. You must select a separate Alco ASC3 or equivalent coil that matches your specific system voltage (e.g., 24V, 120V, or 208/240V).

What are the refrigerant capacity ratings for this valve?
This valve is rated for 1.27 tons on R22 and 1.2 tons on R134a. It is also compatible with R407C, R404A, and R507 systems where flow requirements match these specifications.

Can this valve be mounted in any orientation?
While it can be installed in horizontal or vertical lines, it is recommended that the enclosing tube is not mounted more than 90° off the vertical upright position for optimal plunger operation.
