Emerson Alco 065620 Solenoid Valve

The Emerson Alco 065620 (Model 200RB3T3M) is a heavy-duty, pilot-operated refrigeration solenoid valve designed for demanding liquid, discharge, or suction gas service. As a 2-way normally closed solenoid valve, it features an integrated manual stem, an essential feature for technicians needing to manually override the valve or keep it open during system evacuation and emergency bypass scenarios. Built with 3/8 inch ODF extended solder ends, this valve allows for quick brazing without the risk of internal component damage from heat, ensuring a clean and reliable installation on the job site.

This HVAC solenoid valve is engineered for high-performance refrigerant management, delivering a nominal R22 capacity of 4.8 tons and compatibility with R134a (3.6 tons), R407C (4.5 tons), and R12 (3 tons). The 200RB3T3M utilizes a 3/16 inch port and is distinguished by its PTFE O-ring, which provides superior external sealing against modern synthetic oils and high-pressure refrigerants. It is rated for a Maximum Working Pressure (MWP) of 500 psig and a Maximum Operating Pressure Differential (MOPD) of 300 psig, making it a rugged choice for both commercial refrigeration and air conditioning systems where precise flow control is non-negotiable.

• Enhanced Serviceability: The built-in manual stem allows for simplified troubleshooting and manual system operation without needing to energize the coil.
• Versatile Compatibility: Designed for an extensive refrigerant range, including R22, R134a, and R407C, catering to both legacy and modern equipment.
• Flexible Installation: Extended copper ends permit direct brazing into the line, while the universal design means one coil fits all valve sizes in the 200RB series.
• Leak Protection: High-grade PTFE O-rings and long-life molded coils ensure maximum durability and a leak-free seal under high-thermal stress.

Is the coil included with the 200RB3T3M?
Standard 200RB series bodies are typically sold as Valve Less Coil (VLC). You must pair this body with an ASC2, AM, or DM coil depending on your voltage requirements.

Can this valve be used for bi-flow applications?
In its standard normally closed configuration, this is a uni-directional valve. However, it can be converted to bi-flow operation using the appropriate Emerson conversion kit (KS30387).

What is the purpose of the manual stem on this specific model?
The "M" suffix indicates a manual lift stem, which is critical for opening the valve during high-vacuum evacuation or in the event of a power failure to prevent system downtime.
