The Emerson Alco 053105, model 200RB2T2VLC, is a pilot-operated 1/4" 2-way normally closed solenoid valve engineered for precision refrigerant flow control in high-pressure commercial systems. Designed with a rugged extended copper connection, this valve allows for brazing without disassembly, maintaining internal seal integrity. It serves as a direct technical replacement for the Sporlan 3238-00 E5S120, ensuring seamless integration into existing liquid, suction, or discharge lines. Rated for a Maximum Working Pressure (MWP) of 680 psig and compatible with HFC, HCFC, and CFC refrigerants including R-410A and R-404A, the 200RB series utilizes a PTFE valve seat for bubble-tight shut-off. This HVAC solenoid valve requires a minimum pressure drop for operation, making it ideal for standard refrigeration cycles where reliability and fast response times are critical. Technicians favor this model for its high MOPD capabilities and the ability to service internal components without removing the body from the piping. Key Technical Benefits Extended ODF Connections: Simplifies installation by allowing direct brazing, protecting the internal solenoid components from heat damage. Field Serviceable Design: The top-entry configuration allows for rapid inspection and replacement of internal valve parts, reducing downtime on site. High MOPD Rating: Engineered to open reliably under high pressure differentials common in R-410A systems. Synthetic Seat Material: The PTFE seat ensures a positive seal across a wide temperature range, preventing refrigerant bypass. Common Installation & Application Questions Is the 200RB2T2VLC compatible with POE oil? Yes, the materials used in this Emerson Alco solenoid valve are compatible with both mineral and POE lubricants found in modern refrigeration systems. Which coil is required for this solenoid valve? This valve body is designed for use with Emerson ASC2 series coils; ensure you match the voltage and frequency to the specific job site requirements. Can this valve be mounted in any orientation? For optimal performance and to prevent debris accumulation, it is recommended to install the valve with the solenoid coil in a vertical upright position.
