Emerson Alco 066184 Solenoid Valve

The Emerson Alco 066184 Solenoid Valve, now identified by the direct replacement 049162 (Model 200RB4T3T), is a 2-way normally closed, pilot-operated valve designed for high-performance refrigeration and air conditioning systems. Engineered for reliability, this refrigeration solenoid valve features a 3/8" ODF sweat connection and includes a mounting stud for secure installation. With an 8.0 Ton R22 capacity and 6.0 Ton R134a capacity, it is compatible with various refrigerants including R-407C, R-404A, and R-507. This pilot operated solenoid valve utilizes a 200RB series body, known for its high-flow capacity and low-pressure drop across the seat. As a normally closed solenoid valve, it ensures tight shut-off during the off-cycle, preventing refrigerant migration. When replacing an older Alco 066184, transitioning to the 200RB4T3T ensures modern manufacturing tolerances and robust performance in liquid, discharge, or suction line applications.

• Maximum Fluid Compatibility: Designed for use with CFC, HCFC, and HFC refrigerants, providing versatility across diverse field installations.
• Enhanced Flow Dynamics: The pilot-operated diaphragm construction allows for high R22 cooling capacity while maintaining minimal pressure differentials.
• Simplified Installation: Features extended 3/8" copper tails for easy brazing and a dedicated mounting stud to reduce vibration and mechanical stress.
• Heavy-Duty Construction: Built with a rugged brass body and stainless steel enclosed tubes to ensure long-term mechanical integrity in demanding environments.

What is the direct replacement for the Emerson 066184?
The current industry-standard replacement for the 066184 is the 049162, also categorized under the 200RB4T3T model designation.

Is the coil included with the 200RB4T3T solenoid valve body?
This item consists of the valve body and mounting stud only; a compatible ASC2 solenoid coil must be sourced separately based on your specific voltage requirements.

Can this valve be mounted in any orientation?
For optimal performance and to prevent debris accumulation in the pilot assembly, it is recommended to install the valve with the coil in a vertical-upright position.
