Emerson Alco 054170 Solenoid Valve

The Emerson Alco 054170 Solenoid Valve (model 200RB2T3T) is a professional-grade, pilot-operated refrigeration solenoid valve designed for high-reliability flow control in commercial and industrial systems. Built with a normally closed configuration, this 2-way valve body features 3/8" ODF sweat connections with copper extended ends, allowing for streamlined brazing without disassembly. This specific model is equipped with a mounting stud for secure mechanical installation, effectively reducing vibration stress on the piping.

Engineered for versatile media handling, the 200RB series is rated for liquid line, suction, or discharge gas service. It delivers a nominal R22 capacity of 3.6 tons and an R134a capacity of 2.7 tons (at standard ARI conditions). With a Maximum Operating Pressure Differential (MOPD) of 300 psig and a robust maximum working pressure of up to 680 psig, this 1/8" port size valve maintains consistent performance across various refrigerant classes including A1, A2L, and A3. The internal PTFE O-ring ensures a superior external seal, while the pilot-operated piston design provides the necessary lift even in low-pressure drop scenarios.

• Interchangeable Coil System: Compatible with a single coil family (ASC2, AM, DM) across the entire 200RB range, simplifying truck stock and field replacements.
• Extended Sweat Ends: The 3/8" copper stubs facilitate faster refrigeration solenoid valve installation by keeping heat away from internal seals during the brazing process.
• Mounting Stud Configuration: Includes a factory-installed stud for rigid mounting, preventing line sag and reducing audible resonance in professional HVACR systems.
• Durable Sealing: Features a PTFE O-ring and long-life molded components to prevent refrigerant leaks and ensure long-term seat integrity.

• Is the coil included with the 054170? No, this is a VLC (Valve Less Coil) body. You must select the appropriate voltage coil separately.
• What is the proper mounting orientation for this valve? For optimal operation, the valve should be mounted in a horizontal or vertical position with the coil upright; upside-down installation is not recommended.
• Can this valve be used for bi-flow applications? While the standard 200RB2T3T is uni-directional, it can be converted to bi-flow service using a KS30293 conversion kit for heat pump applications.
