Emerson Alco 047507 Solenoid Valve

The Emerson Alco 047507 Solenoid Valve (model 200RB4F3M) is a rugged, pilot operated refrigeration solenoid valve designed for heavy-duty liquid, discharge, or suction gas service. As a 2 way normally closed component, it provides reliable flow control for high-capacity systems, featuring a nominal R22 capacity-8.0 Ton and R134a capacity-6.0 Ton. This specific model is equipped with a 3/8" flare (SAE) connection and a manual stem, allowing technicians to manually override the valve during system troubleshooting or emergency bypass operations.

Built for the rigors of commercial HVACR environments, the 200RB series valve body utilizes a high-grade PTFE O-ring for superior external sealing and a molded coil design that resists moisture and vibration. With a Maximum Working Pressure of 500 PSIG and an MOPD of 300 PSIG, this normally closed solenoid valve ensures tight shut-off and high performance across various refrigerants, including R-404A and R-507. Its pilot operated piston design requires a minimum pressure drop of only 2 psi for full opening, optimizing efficiency in both refrigeration and air conditioning circuits.

• Enhanced Serviceability: The integrated manual stem allows for manual opening during maintenance or power failures without requiring magnetic tools.
• Optimized Performance: Specifically rated for R22 capacity-8.0 Ton and R134a capacity-6.0 Ton to meet the demands of commercial evaporators and condensers.
• Universal Coil Compatibility: Designed to work with the Emerson ASC2 and AM coil families, streamlining inventory for the contractor.
• Reliable Sealing: Features a durable PTFE O-ring and stainless steel enclosing tube to prevent leaks in high-vibration 3/8" flare connections.
• Broad Application Range: Suitable for liquid line, suction line, and discharge gas service across multiple A1, A2L, and A3 class refrigerants.

• Does this valve come with a solenoid coil? No, this is a Valve Less Coil (VLC) body. You must purchase an ASC2, AM, or DM series coil separately to match your system voltage.
• Can this 200RB4F3M be used in bi-flow applications? While the standard 200RB is uni-directional, it can be converted to bi-directional operation using a KS30293 conversion kit for heat pump applications.
• What is the purpose of the 'M' suffix in the model number? The 'M' indicates the inclusion of a manual opening stem, which is critical for system evacuation or manual testing.
