Emerson Alco 064063 Solenoid Valve

Professional-grade refrigeration systems require dependable flow control, and the Emerson Alco 064063 (Model 200RB7T5) delivers consistent performance in liquid, suction, or discharge gas service. As a pilot-operated, 2-way normally closed solenoid valve, this unit is engineered for high-capacity applications, offering a nominal R22 capacity of 17 tons and an R134a capacity of 12.7 tons. The 5/8" ODF sweat connections feature extended ends, allowing technicians to braze the valve into the line without disassembly, protecting internal components from heat damage during installation.

The Emerson 200RB series is designed with field serviceability in mind, utilizing a single coil family (compatible with ASC2, AM, and DM coils) to simplify inventory for contractors. With a Maximum Operating Pressure Differential (MOPD) of 300 psig and a maximum working pressure of 500 psig, this solenoid valve body ensures reliable shut-off in demanding HVACR environments. Its PTFE O-ring and rugged construction provide superior external sealing, making it a staple for large-scale refrigerant flow control. Note: this is a Valve Less Coil (VLC) model; coils must be sourced separately based on your specific voltage requirements.

• Streamlined Installation: Extended copper ends permit direct brazing, reducing labor time and the risk of internal seal distortion.
• High-Capacity Performance: Optimized for large R22 and R134a systems, providing 17-ton and 12.7-ton capacities respectively.
• System Versatility: Ideal for liquid line, suction line, and hot gas discharge refrigerant service.
• Simplified Maintenance: Features field-serviceable parts and a standardized coil family for faster troubleshooting and repairs.
• Robust Sealing: Equipped with a PTFE O-ring to maintain vacuum integrity and prevent external leaks in high-pressure systems.

Is this valve bi-directional for heat pump applications?
Standard 200RB7T5 models are uni-directional. While some 200RB valves can be converted for bi-flow use with a kit, the size 7 and 9 bodies typically do not support this conversion; always verify the specific flow requirements of your system before installation.

What coil should I use with the 064063?
This valve body is compatible with the Emerson ASC2, AM, or DM series coils. Selection depends on your system’s control voltage (e.g., 24V, 120V, or 240V).

Can this valve be mounted in any orientation?
For optimal performance and to prevent plunger sticking, it is recommended to mount the valve in a horizontal or vertical line with the coil in an upright position. Mounting upside down is not recommended.
