Emerson Alco 049164 Solenoid Valve

The Emerson Alco 049164 Solenoid Valve (model 200RB5T4T) is a high-performance, 2-way normally closed pilot-operated valve designed for rigorous industrial and commercial refrigeration service. This refrigeration solenoid valve body features 1/2" ODF sweat connections with copper extended ends, allowing for straightforward brazing without the need for valve disassembly. Optimized for high-capacity systems, it delivers a nominal R22 capacity of 8.2 tons and an R134a capacity of 6.2 tons, ensuring precise flow control for liquid, suction, or discharge gas applications. The integrated mounting stud provides a secure mechanical anchor, reducing vibration-induced fatigue in the piping. Built with a PTFE O-ring for superior external sealing and a maximum working pressure of 500 psig, this valve is compatible with modern A1 and A2L refrigerants. This is a VLC (Valve Less Coil) configuration, allowing contractors to pair it with any standard Alco solenoid coil to match specific voltage requirements and 25 bar MOPD performance standards.

• Extended ends facilitate fast, safe installation by eliminating the need for internal disassembly during the brazing process.
• Universal coil compatibility allows a single coil family to fit all 200RB series valves, simplifying truck stock and emergency replacements.
• High MOPD rating of 300 psig ensures reliable opening even under high differential pressure conditions typical of hot gas service.
• Durable piston design and pilot-operated mechanism provide consistent shut-off and long-term reliability in contaminated or high-cycle systems.
• Mounting stud utility minimizes line stress and ensures the solenoid valve remains stable during high-velocity refrigerant flow.

Does this valve come with the electrical coil?
No, this is a Valve Less Coil (VLC) body. You must select and install the appropriate Alco ASC or ESC coil based on your system's voltage requirements (e.g., 24V, 120V, or 240V).

What is the maximum operating temperature?
The 200RB5T4T is rated for a maximum fluid temperature of 250°F, making it suitable for discharge gas and liquid line applications.

Can this valve be mounted in any orientation?
Standard practice requires mounting with the coil in the vertical-up position. You should not mount the enclosing tube more than 90° off the vertical up position to prevent malfunction or debris accumulation.
