Description
The Copeland 047503 (100RB2S2) is a direct acting, 2-way normally closed refrigeration solenoid valve body engineered for reliable flow control in commercial and light commercial refrigeration systems. With a compact 1/4″ sweat connection and direct-acting design, this valve opens and closes without relying on line pressure differential, making it suitable for low-pressure-drop and pump-down applications.
Key Features
- 2-way, normally closed configuration — valve closes when de-energized for fail-safe operation
- Direct-acting design operates independently of inlet pressure differential
- 1/4″ sweat (ODF) connection for easy copper tubing installation
- Compatible with R-22 refrigerant at a rated capacity of 1.27 tons
- Compatible with R-134a refrigerant at a rated capacity of 1.20 tons
- Valve body only — coil sold separately for flexible voltage selection
- Ideal for pump-down circuits, liquid line shutoff, and refrigeration flow control
Refrigerant Capacity
- R-22: 1.27 Ton
