Copeland Comfort Control (Alco) 049609 Solenoid Valve

The Copeland Comfort Control (Alco) 049609 Solenoid Valve, also identified by model 200RB3T3, is a heavy-duty, 2-way normally closed solenoid valve engineered for precision flow control in commercial refrigeration and HVAC systems. This pilot-operated valve is designed for high-side or low-side applications, including liquid, suction, and discharge gas service. With its 3/8" ODF (Sweat) connections featuring extended ends, it allows for easy brazing without requiring valve disassembly. This unit serves as a direct upgrade and replacement for legacy models 066161 and earlier 200RB series iterations.

Constructed to withstand the rigors of field operation, the 049609 features a 500 psig Maximum Working Pressure (MWP) and a 300 psig Maximum Operating Pressure Differential (MOPD). Technical specs include a nominal R22 capacity of 4.8 tons and an R134a capacity of 3.6 tons, making it a versatile choice for medium to large-scale evaporative systems. The use of a PTFE O-ring ensures a superior external seal, while the bracket-mounted design provides stability even under high-vibration conditions common in rack systems and rooftop units.

Key Benefits for Contractors

• Universal Compatibility: Designed to work with standard ASC2 series solenoid coils, allowing for flexible voltage configurations in the field.
• Reduced Pressure Drop: Requires a minimum operating pressure drop of only 2 psi for reliable pilot opening, ensuring system efficiency.
• Serviceability: The extended sweat ends protect the internal PTFE components during installation, preventing heat damage to the seat.
• Environmental Resilience: Features a maximum fluid temperature rating of 250°F, suitable for demanding hot gas defrost or discharge line applications.
• Proven OEM Quality: Meets UL/CUL File MP604 standards for industrial-grade refrigeration components.

Common Questions

What is the difference between the 049609 and 200RB3T3?
They are the same component. 049609 is the Copeland/Alco service part number, while 200RB3T3 is the technical model designation specifying the 3/8" ODF connection size and valve series.

Can this valve be used for bi-flow applications?
While some 200RB models support bi-flow, the 200RB3T3 is typically configured as a standard 2-way normally closed valve. If bi-flow is required for heat pump applications, verify the specific internal assembly or manual stem configuration before installation.

Is the coil included with the valve body?
No, this is the valve body only. You must pair it with the appropriate Alco ASC2 coil matching your system's control voltage (e.g., 24V, 120V, or 240V).
