Copeland Comfort Control (Alco) 047544 Solenoid Valve

The Copeland Comfort Control (Alco) 047544 Solenoid Valve, also known as the 200RB6T4, is a heavy-duty, pilot-operated refrigeration solenoid valve designed for high-capacity liquid, suction, or discharge gas service. This 2-way normally closed solenoid valve features a 1/2" sweat connection ODF (Over Deluxe Fitting) to ensure leak-proof integration into commercial refrigeration and HVAC systems. Built for durability in demanding environments, it supports a wide range of refrigerants, offering an R22 capacity of 9.5 tons and an R134a capacity of 7.2 tons. The pilot-operated diaphragm construction allows for reliable opening even under high-pressure differentials, making it a standard choice for technicians managing larger tonnage systems. It is compatible with Copeland Alco AMG and ASC2 solenoid coils, providing a versatile solution for precise refrigerant flow control and system isolation.

Key Benefits for Contractors

• Optimized Flow Control: The normally closed configuration ensures positive shut-off during system standby, preventing refrigerant migration to the compressor.

• Versatile Media Handling: Certified for use with liquid lines, suction lines, and hot gas discharge, reducing the need to stock multiple valve types.
• Field Serviceable: The Alco 200RB series design allows for easy maintenance of internal components without removing the valve body from the piping.
• Wide Refrigerant Compatibility: Designed to perform with R22, R134a, R404A, R407C, and R507.

Common Questions

What coil should be used with the Alco 200RB6T4?
This valve body is designed to work with ASC2 or AMG series coils. Always verify the voltage requirements of your specific controller before installation.

Can this valve be installed in any orientation?
For optimal performance and to prevent debris accumulation, it is recommended to install the valve with the coil in the upright vertical position; however, it can be mounted horizontally if necessary, provided the coil is not below the valve body.

Is the 047544 compatible with modern HFC and POE lubricants?
Yes, the Copeland 047544 features synthetic seating materials specifically chosen for compatibility with modern refrigerants and POE oils found in current HVACR systems.
