Description
The Copeland 049186 (200RB4T3M) is a pilot operated refrigeration solenoid valve body engineered for reliable, precise flow control in commercial and industrial refrigeration systems. Featuring a 2-way, normally closed (NC) design, this valve remains closed when de-energized, opening only when the coil is energized — providing a fail-safe shutoff that protects your system during power interruptions.
The 3/8″ sweat connection ensures a leak-tight, permanent installation compatible with standard copper tubing, while the manual stem allows technicians to manually open the valve for service, startup, or emergency bypass without energizing the coil.
