Emerson Alco 061227 Solenoid Valve

The Emerson Alco 061227 (Model 200RB5T3) is a high-performance pilot operated refrigeration solenoid valve body designed for liquid, discharge, or suction gas service. This 2-way normally closed valve features 3/8" ODF sweat connections with extended solder ends, allowing for installation without dismantling the valve, effectively protecting internal components from heat damage during the brazing process. Rated for substantial capacity, it delivers 8.2 tons for R22 and 6.2 tons for R134a systems, making it a versatile choice for commercial refrigeration and air conditioning plant maintenance. The 200RB series utilizes a single ASC2 or AM coil family across its range, simplifying truck stock and ensuring rapid field serviceability. Built to withstand demanding environments, this valve has a maximum working pressure (MWP) of 500 psig and a maximum operating pressure differential (MOPD) of 300 psig. Its PTFE O-ring provides superior external sealing, while the rugged 2-piece piston construction ensures reliable cycling in refrigeration solenoid valve applications.

Key Benefits:

• Reduced Installation Time: Features extended copper ends (ODF) for direct brazing without valve disassembly.
• Broad Refrigerant Compatibility: Engineered for use with R22, R134a, R404A, R507, and other common A1 class refrigerants.
• High Durability: Equipped with PTFE seals and a pilot-operated piston design to ensure long-term integrity in high-pressure lines.
• Simplified Inventory: Part of a universal body family compatible with Emerson ASC2, AM, and DM solenoid coils.
• Field Serviceable: Internal components are accessible for cleaning or replacement using standard refrigeration service tools.

Common Questions:

Does this valve include the solenoid coil?
No, the 061227 200RB5T3 is a VLC (Valve Less Coil) model. You must pair it with a compatible Emerson ASC2 or AM series coil, available in various voltages (24V, 120V, 24VDC) depending on your control circuit requirements.

What is the maximum fluid temperature for this solenoid?
The Emerson 200RB series is rated for a maximum fluid temperature of 250°F, making it suitable for hot gas discharge lines as well as standard liquid line applications.

Can this valve be used for bi-flow operation?
While the standard 200RB5T3 is uni-directional, it can be converted for bi-directional flow in heat pump applications using the KS-30293 conversion kit.
